Same here, and McCain, and Romney...
Bush the father, Dole, Bush the son, McCain, Romney...I need a drink...
I was moving between states in 2008 and couldn't register in time to vote for McCain. I don't recall it bothering me too much.
I was out of the country on an emergency trip in 2012 and missed voting for Romney. I don't recall that bothering me too much, either.
But I made a big effort to vote for Donald Trump, twice.
2024? Cruz/Noem would probably motivate me to make an effort. Serve up Haley/Rubio and I'll have to schedule another foreign trip. :)
