The first election I was old enough to vote in was 1996. I voted for Clinton without hesitation. I liked his administration and I liked most of Clintonomics, other than the push to lend to unqualified borrowers simply based on ethnic background. The idea was a good one, but it wasn't properly regulated and was a huge driver of the most recent recession.
In 2012, I voted for Obama over Romney. I wasn't wild about Obama, but I didn't like or trust Romney, and after watching Biden absolutely rout Paul Ryan in the V.P. debate, I didn't feel comfortable with Ryan being involved in policy at such a high level.
Last, while I know this wasn't technically part of your question, I voted for Harold Ford (Jr.) for the House. I lived in Memphis and knew him - I liked him.
