To best examine how my views have changed, you should look at candidates I've supported in the past:
2008 Democratic primaries: Hillary Clinton
2008 general election: John McCain/Sarah Palin
2012 Republican primaries (before people actually started campaigning) Sarah Palin, Mitt Romney, Gary Johnson, Ron Paul, Mike Pence, Mitch Daniels
2012 Republican primaries (after people actually started campaigning) Herman Cain, Buddy Roemer, Rick Perry, Newt Gingrich, Rick Santorum, and currently Buddy Roemer again
2012 Libertarian primaries: Gary Johnson
So, basically, coming off from this...I started out as a moderate liberal who got angry when Obama won the Dem nomination in '08. Then McCain picked Palin as his veep and I "saw the light", becoming pretty much a generic conservative. Somewhere down the line, I adopted a mild libertarian bent that has slowly become more and more pronounced. As of right now, I've had another "seeing the light" kind of experience and have left the outright conservative crowd for good. Libertarian.
