I'll take the flaming. If Paul doesn't win the GOP nod, there's a very good chance I'll vote for Obama. Why?
The way I see it, both parties are going to be wasting immense amounts of money on stupid projects we don't need. The difference is the Democrats will be more apt to waste it on projects here that might have some marginal impact, the Republicans abroad on unconstitutional wars. I'm not going to pretend the Dems have a better record about that, because they don't, but bellicose imperialism isn't something they enjoy either.
There will always be a party, in a democracy, believing that government needs to take care of the people. The Democrats are that party, represent what is a coherent world view based upon a certain understanding of human nature. It is not one most Paulites share, but that is another argument. While not agreeing with everything, I can accept this.
As for the Republicans, they are a party that claims to support limited government and does nothing to support it in fact. I worked as a GOP committee recruiter, have run for office, and had many conversations. I've met theocrats, opportunists, zealots, users, and a few good people searching for a party better than what they are getting. A Republican President not named Paul will inevitably lead us into a bloody conflict resulting in the loss of many American lives, increased risks of blowback related terrorism, and I'm not willing to accept that.
Obama is a disappointment on many levels. I did not vote for him in '08. But he's saner than the alternatives, and odds are, he'll get my vote with distaste. My biggest concerns with him are on civil liberties, but it heartens me to know most Democrats I know are upset about those things also, and I'm hopeful for improvements on that basis alone.
I respect those who vote third party. I agree more closely with a libertarian, though I'm not a libertarian on economics. But I'm not going to be a protest vote if this comes down to a two way race.
I don't believe the Republicans will ever change until they learn what they present is unacceptable, and making them lose is fine by me. The reset button has to be hit one way or the other. Romney would just prolong a system that is broken, so why not let things play out to their end?
I don't expect most people here to agree, but I've talked to enough people who like RP to know I'm not the only one who thinks this way, though I'm probably the only one who posts here with any frequency.
