I consider myself a libertarian/conservative. Like many people of that bent, I was uncomfortable with Bush when he was nominated. But Al Gore's increasingly-erratic behavior during the 2000 election made me hope Bush won.
Once Bush won, and it became clear that the Florida democrats were trying to steal the election, I became something of a Bush loyalist. Throughout his first term, I took note of all the really horrible things that were said about him, saw that a large portion of the left would rather see Bush fail than see America succeed, and was alarmed by the complicity (and often, participation) of the MSM and mainstream Hollywood. It wasn't far into his second term that I succumbed to Bush Fatigue, due to his inability to make the case for his foreign policy to the American people, and his inability to find the veto pen. He has truly been a terrible steward of the Republican brand, and because of this, the Conservative and libertarian causes are suffering.
I'm no fan of McCain , but as I dislike Obama, I'll be pulling the lever for McCain in November.
This is surely small of me, but if Obama wins, I plan on giving him as much of a chance as the Democrats gave George Bush. I will gleefully forward every paranoid anti-Obama rumor that I see, along with YouTube footage of his verbal missteps. I will laugh and email heinous anti-Obama photoshop jobs, and maybe even learn photoshop myself to create some. I'll buy anti-Obama books, and maybe even a "Not My President" t-shirt. I'm sure that the mainstream bookstores won't carry them, but I'll be on the lookout for anti-Obama calendars and stuff like that. I will not wish America harm, and if the country is hurt (economically, militarily, or diplomatically) I will truly mourn. But i will also take some solace that it occurred under Obama's watch, and will find every reason to blame him personally and fan the flames.
Obama's thuggish behavior thus far in this election cycle - squashing free speech, declaring any criticism of his policies to be "racist" (a word that happily carries little weight with sensible people these days), associating with the likes of Ayers, Wright, and ACORN - suggests that I won't have to scrape for reasons to really viscerally dislike Obama and his administration. And even if he wins, his campaign's "get out the vote fraud" activities are enough to provide people like me with a large degree of "plausible deniability" as to whether he is actually legitimately the president.
I've seen a President that I am generally-inclined to like get crapped on for eight years, and I've seen McCain and Palin (honorable people both, despite policy differences I may have with them) get crapped on through this election season. If the Democrats think that a President Obama is going to get some sort of honeymoon from the folks who didn't vote for him, as a wise man once said: heh.
