2012: Gary Johnson
2016: Gary Johnson
As for state-wide races (in New Mexico), I voted for Susana Martinez for governor in 2014 (though I've grown to like her less since then), and a mix of Republicans and Democrats for Senate/Congress/City council etc. I supported Republican Dan Lewis for Albuquerque mayor in 2017 and he lost, but the Democrat who won (Tim Keller) seems OK. I think Bill Richardson was a better governor than Susana and I think Martin Chavez (both Dems) was a better mayor than Republican former mayor Richard Berry.
Since I'm young, I looked back and did an experiment to see who I would've voted for in past elections:
1980: Reagan
1984: Reagan
1988: Bush
1992: Perot
1996: Perot
2000: Nader
2004: Michael Badnarik
2008: Chuck Baldwin
Like Leon, I've kinda been over the place politically, trying to figure out what I really believed in and who/what best represented my views. If I had to classify myself now I would say I'm a slightly conservative-leaning Libertarian, but I'm registered as an independent voter. I generally dislike both major parties, but prefer the Republicans slightly (sometimes).
I'm willing to vote for anyone who I feel has the temperament and willingness to work together with others for President. In 2016 I would've voted for Rand Paul (for sure, he was my # 1 choice), or maybe Kasich, Rubio, or Jeb Bush. I would never, ever vote for Trump. I liked Ted Cruz as first for his anti-establishment views, he was Libertarian-ish (at first), and thought he was intelligent and articulate. But he lost me when he started getting desperate in the primaries and I found out he was too socially conservative for me, and looking back he seemed to be a bit too stubborn when it came to getting his way (i.e the government shutdown in 2013), though it was admirable to me in a sense.
On the Dem side, I would've voted for Jim Webb also. Maybe I would've considered Biden, same with O'Malley. I respected Sanders but he was too far left for me. I would never, ever vote for Hillary.
So once Trump and Hillary became the nominees the choice for me was pretty clear. During the campaign I preferred Trump a bit, but now that he's actually President I'm not so sure anymore. Meh. The two people I liked the least got the nominations.
