As you already know there are no real Independents ~ but getting a Democrat to vote for Romney would be the trick of the century. More likely they won’t vote for either one.
From what I gather of FReepers’ perceptions of Romney, he should draw more white Dems than Repub voters; he is clean, articulate, and doesn’t speak with a Negro accent (which sufficed for many Dems in voting for Obama).
In tough financial straits, only the far left stays with the Dems; the rest grudgingly accept that the only way their neighborhoods are safe, taxes stabilize, etc. is to vote for the adult (the Republican). FWIW, the Dem Party of 2012 is far different from that of 2008; it is openly at war with the Christian right (especially Catholics), openly including “gay marriage” in the official party platform, publicly insisting things are OK economically, and doesn’t even mask the socialist agenda. Why would anyone (from welfare queens to union members) ever vote for Obama?
