who is maybe the perfect reflection of what everyday conservatives have become, ignorant, stupid, and incredibly well off while whining about how they’re not well off enough.
I wouldn't say they're that representative of a lot of everyday conservatives. A lot of them are doing pretty poorly, but they're ignorant and get pissed off at the idea that anyone else might benefit from a program they personally don't qualify for or disagree with. My father is absolutely convinced that if the Democrats had the political will and ability to implement a wealth tax, that he would somehow be absolutely murdered by taxes on his $10 or $11 an hour he's making at a Winn Dixie in Florida. He's also the sort convinced that welfare queens living it up with brand new cars and designer clothes are not just a real thing, but a common thing that happens that Democrats just don't want people to know about. He'd probably also chalk up his retirement sucking due to what limited social safety net we have in the US, rather than him draining his retirement accounts while he was unemployed before hitting retirement age so he could play golf and go hang at the bar with his buddies even though he was broke. Medicare is his right, though, he worked for that and earned it, but screw these poors under 65 trying to get healthcare with Medicaid. About the only thing he's missing for your average, everyday conservative is an unhealthy dose of religion.
Could just be that you can only run so many campaigns in a row with "If you don't vote for us, it's going to be the end of the world as we know it. And at least I'm not as bad as the other guy." With the exception of Obama's first run against McCain, that's been the pitch for every single election I've ever been able to vote in, as well as a few before it. It gets old real quick, makes them come off as insincere, and doesn't motivate anyone when we're still largely dealing with the same BS issues that we were 20 years ago.
Trying to browbeat people into voting with the same old song and dance has diminishing returns, especially when your candidate is increasingly out of step with many of the voters they should be courting on major issues.
