I don't want to be cynical but they'll just blame liberals for there problems even you pointed out despite the obvious horrible job in Kansas Brownback did he still won because these people only care about "god and guns"
To be fair, I did acknowledge that he just barely won. The problem is, Kansas is reliably and deeply Republican, but for Brownback to even skirt that close to a loss in a GOP wave year under an incumbent Democratic president that is unpopular in Kansas, well, that is pretty bad.
You're actually not that wrong on the blame shifting, though. There are studies about this. Partisanship and political identity is deeply embedded, and many diehard partisans will often reject ideas that challenge their views and look elsewhere for an answer. But, even this can only take so much.
There are VERY elastic limits to such gullibility though. Especially in the Fox News/Internet bubble we live in today for info sources. Most people don't fact check their news source. The TV tells them Obamacare was collapsing to begin with and the loss of coverage resulted, so Pricecare came in to salvage what was left yadda yadda yadda ---sadly close to 90% of the audience will likely accept it as basically true.
