The three greatest mistakes of my life-
1. Personal
2. Being fooled by and voting for John McCain
3. Being fooled by and voting for Mitt Romney
Right there with you! I even gave money to McCain...
MFO
I was never fooled by either one of them but voted for them none the same
I agree with your list but I would also add (for me) voting for W—he ended up being a HUGE disappointment. He was better than The Goron, and John F*ing Kerry, but not much better.
1. Getting married. (She was as worthless a wife and mother as there ever was.)
2. Holding my nose and voting for McCain
3. Holding my nose and voting for Romney.
In retrospect, it's actually a half-way good thing that Obama beat Romney in 2012 because without that we wouldn't have gotten President Trump. :-)
