Okay, I've given my technical analysis; now for my personal opinions.
This is an odd year, because while I lean a little to the right (more on economic than social policy), I'm actually very hesitant about many of the Republican candidates. Huckabee's done everything he can to avoid talking about the issues during the debates - the "I did this" evasion gets old after the first eight times. Ron Paul seems outright nuts to me in more ways than one, and it's irrelevant since he's not getting the nomination anyway. Giuliani might be a good choice if he actually had a snowball's chance of winning. McCain's a strange choice, because while I agree with most of his calls on the war, in everything else he's basically a Democrat. That leaves Romney as the only decent choice for me.
The other side is simpler. Hillary outright scares me, and Edwards seems way too conniving somehow. I don't agree with many of Obama's positions, but at least he seems like he has some semblance of honor. That's more than I can say for many of the Republicans, really.
This leaves an interesting series of potential choices come November. Should Hillary or Edwards get the Democratic nod, I'll vote for anyone who opposes them (except maybe Paul). But if Obama wins it, my final vote depends on who he's facing. If it's Romney, I'll stick with him. Paul would probably prompt a Democratic vote, and even Huckabee might do the same. I'm unsure about McCain and Giuliani at this point, too.
Gotta love scenario politics. It's like watching a baseball playoff race.
EDIT: Roy, let me remind you that Hillary's claiming to have 35 years of experience in politics. Enough said.
