@DrewDad,
Something more meta I've been thinking of, not sure I can articulate it all the way:
Obama has stayed consistent throughout his campaign and presidency on being moderate, reasonable, willing to compromise. He owns that.
So, how does one run against that? As in, if you just plain don't like him and want him out, what is the contrast? Immoderate, unreasonable, unwilling to compromise.
That's what a lot of the candidates look like right now.
I don't think that will fly with independents and more moderate voters.
I'm very curious what Romney will end up doing with all of this. He's generally more reasonable and moderate than most -- will that freeze him out this cycle? Will he figure that his chances are low and rather than losing twice in a row, sit this out and wait for 2016? Will he go extremist and unreasonable just through the primaries and then dial it back if he gets the nomination?
