A truly terrible day, IMO.
A hazard I tried to capture above is that perhaps charisma and ideology should not be treated as altogether independent variables. The memetic twist of perspective is that one thinks not of people acquiring beliefs, but of beliefs acquiring people. There's a saying, that an idea is not responsible for the people who believe in it — but in memetic thinking, an idea is responsible (statistically, of course) for the people who believe in it. It seems like in this US election cycle a whole bunch of extreme-right politicians said really stupid things (in a generous mood one might say, politically stupid); in the memetic view, one considers that as a property of the ideology.
(I apologize for the extended delay in my response -- I've been bogged down with RL these past few weeks, but hopefully the momentum of an interesting discussion isn't completely dissipated).
I'm inclined to agree that the delivery of ideology is based mostly, if not wholly, upon a candidate's level of charisma. This, while it does not result in ideology and charisma becoming independent variables (I agree with you in that regard) is proof (in my mind, at least) that charismatic candidates consistently do better electorally and politically among swing voters (who, needless to say, decide the outcome in close elections) than their less charismatic counterparts. Take the U.S. Senate race in Missouri. As you wrote above, the GOP nominated several less than nominal candidates (and that's the optimistic way of putting it) in races that should have been easy wins. Todd Akin would have won the Missouri (a red state) race had he not made his politically fatal gaffe about abortion. The result was a Democratic hold in a red state that really should have been (according to all conventional political logic) an easy pick-up. The exact same thing took place in Indiana, where Richard Mourdock's far-right wing views alienated the right-leaning (they're most certainly not hard-right, to be sure) independents in the state, resulting in a Democratic pickup in another red state (one would suspect, however that Donnelly will be one of the more vulnerable incumbents in 2018, unless of course the GOP puts up another gaffe-generator).
Thus, while charisma and ideology aren't independent variables, it's charisma (or the lack thereof) that made the difference in these races--not just ideology. Mourdock's and Akin's apparent lack of charisma (in a broad sense, meaning the ability to avoid putting one's foot in his mouth) is what pushed (for lack of a better term) these very slight right-leaning independents (especially those with moderate social views) to assume these off-color moments are part of the ideology and subsequently vote the other way. What it all comes down to among the politically non-inclined, in my mind, is charisma or the lack thereof.
If ideology causes charisma, or lack thereof, then saying that charisma decided a race becomes a distraction from the role that ideology played in the race. And this sort of distraction is something to be wary of because, honestly, the US political right is seriously into denial of the role of ideology in the election. The most insightful thing about the election, imho, comes in two parts: first, that folks on the right (many of them; I'm simplifying, obviously) were shocked Obama won; and second, that folks on the left (...) were bemused that the right were shocked. During the campaign, I think, there had been a general impression on the left that the right were deliberately making shit up that bore no relation to the truth (neither positive nor negative correlation; see w:On Bullshit). The reaction to the election revealed the flaw in that: the word deliberately. I remember a liberal commentator saying about Romney's performance in the first debate, at the time, that he "lied his ass off". That's a perception of intent. But the situation appears to be far more harrowing: a memetic system has formed that allows people trapped inside it to prolifically make up bullshit without being able to recognize they're doing it. Harrowing indeed, because we may be looking at the shape of things to come: first there was oral society, characterized by a certain kind of information propagation, and associated mindset, in which religions flourished; then literate society, characterized by another kind of propagation and mindset, in which sciences flourished (see w:Preface to Plato); and perhaps Internet society will have still other characteristics, with similarities and differences from both orality and literacy.
I seem to have wandered from the relation between charisma and ideology. I could say more on that, but I've written more than enough for now, and won't dilute what I did say with more just now on the other theme.
(Again, my apologies for my delay -- it's a busy time of year).
I remember reading in a book, w:The Selling of the President 1968, in which the argument was made (and I'm more than inclined to agree) that the physical qualities and charismatic abilities of a candidate are almost a sole determinant of his/her success, and that ideology is a sole determining factor in only a very small portion of the population. And that was in 1968. The correlation, I think, is more pronounced now than ever. Now, that's not to say that this applies to every candidate. Negative press and its effect on poll numbers, and a systematic inability to effectively communicate views can be the downfall of any candidate. That said, I couldn't agree more with your argument that the political system of campaigns and elections has evolved to a point where those participating can, time and again, make things up without even realizing they're doing it. It sounds almost Orwell-esque, which highlights the, as you put it, "harrowing" state of affairs. This leads me to believe (and I suspect you might agree) that the media obsession with soundbites is due in large part to the obtuse (in my opinion) response of the public. Call me cynical, but I couldn't help but notice the striking similarities between the 2012 U.S. presidential campaign and one of those reality television talent shows that populate the prime-time airwaves. I follow one closely and have no interest in the other, but yet both feed into this sense of superficiality (it sounds very cynical, I know) that seems to be promoted by popular culture and the media. I guess what I'm saying is that the focus on the delivery of an ideology (and, hence, charisma), rather than the ideology itself is due in large part to the media and, thus, the public (because of the public response it seems to get when a seemingly minor gaffe is relentlessly publicized). To be more specific, I don't think most Republicans make a distinction of "legitimate" and "illegitimate" rape or believe that the female reproductive system "shuts down" in the case of rape. But, because of Todd Akin, a good portion of the public believe otherwise.
The lesson from this discussion seems to be that the world of politics has been absorbed by popular culture and, as a result, candidates are often focusing on showboating and generating memorable soundbites instead of effectively communicating a vision. What I mean is this: a heated televised debate full of soundbites (and, subsequently, lies) between candidates is inherently more interesting to the public than the details of a budget proposal. Because of that fact alone, a substantial portion of the media focuses on the former. And, as long as that progression continues (I think it well), the pattern will only become more and more ingrained in our culture. As dystopian or cynical as it sounds, we're becoming more superficial as a society and we don't even realize it.
I too am very busy. I'm enjoying this leisurely, thoughtful discussion. There's a good chance it'll be a while before I have time to give your latest remark, above, the careful reading it deserves. I'm also aware that this discussion is motivating me to articulate a thought I've been developing for many years but don't yet know how to express well, and I need to give that further thought too. I mean to give a proper reply here; I just don't know whether it'll be today, later this week, or (eying the calendar) next year.
