There will be a segment of the electorate that will go to great lengths to “support” Obama because they are actually supporting themselves as the kind of urbane sophisticates who were evolved enough to vote for a black man as President in racist America. Narcissists all. So you have that bloc, plus the usual lefty knuckleheads looking for their grift.
That's exactly the perception I have of those I know who voted for Obama. Their vote was not really about their country or for that matter even about Obama himself at all. It was about celebrating themselves & enhancing their own view of themselves. Voting for Obama was merely the paternalistic means to the self-serving end of reaching around to pat themselves on the back to congratulate themselves on how virtuous they are for voting for an "African-American" - though ironically they are too racist to see realize he isn't really an authentic A-A, he only looks a little like one! I actually had an in-law admit this to me out loud, albeit unwittingly. She just wanted to be able to vote for a black man to make her feel good, never bothering to trouble her mind that if this nation's first President of color were not to turn out to be a good President how that might adversely impact real african-americans in this country. She could care less about A-A's! It's all about her & her vote for Obama was, as you suggested, an exercise in pure unadulterated naricissim.
You are correct there is a segment that will support him to the bowels of hell rather than admit they were wrong to support him. Fauxbama’s “strongly support” level will stabilize at about 15-20% no matter what he does or how badly he does it,these folks will never ever admit he’s a failure.
As you say they are supporting their own bad judgement in that stand, not neccessarily Fauxbama.
