I look at this in kind of a weird way - I see the question as how would they have voted, hypothetically, in *yesterday's* election. I see them both as being either registered Republicans or not registered at all. My very blue-collar (and fiscally conservative but socially relatively liberal) brothers didn't register to vote until they were well into their 30s, and then they both registered as Republicans. If they were registered, I see them voting all Dems in *this* election. Here's why: Last night I was watching C-SPAN all evening and really enjoying listening to the people all over the country who were calling in to say who they voted for and why. Time and time again, people, mostly men, called into the Republican phone line (you could call that if you considered yourself a Republican, another line if you considered yourself a Democrat and another line if you were "Other") and said something like "I just voted Democrat, and across the board, for the first time in my life. I'm sick of all the lies and corruption and I'm sick of the war." As soon as that trend emerged, I knew our team was gonna win it all. There were also several Republican callers who said they split the ticket by voting all Democrat for Congress and Republican for Governor and other local government.
So in short, I see them registering as Republicans because that's just what you did in both their families (I was once - gasp - a registered Republican myself for that very reason), but voting more and more Democratic as time goes by due mostly to their shared, I think, distaste of the fire and brimstone crowd.
