So, did anyone here vote democratic in 2008, then decide to vote republican this time (or do you know someone who did)?

I'd seriously like to hear what you (or they) have to say, because all I seem to read or hear so far about why this happened is coming from people that I suspect voted the same way both times (on either side). I'd like to hear from the source, the people who chose to switch their votes, why they did so.

*EDIT: I do realize the Reddit community leans to the left (as do I, in interests of full disclosure) and that there may not be many folks here that did this, but I figured it's a place to start.

*EDIT2: Related and also of interest (as per MrFlesh's comment below) - are there any folks that voted in 2008 and chose not to this year? If so, why?
