R is for Republican. I'm married to one. I'm not sure how that happened. When we met in college he didn't look or act like a Republican. We were both against the war (Vietnam) and I'm pretty sure that he voted for Jimmy Carter. We served in the Peace Corps...Republicans don't do that!
I was raised a Democrat. My family supported the civil rights movement and boycotted grapes. JFK was our hero. The spouse's parents supported Nixon. I didn't know that when I married him.
Early in our married life we looked like every other hippie couple in the 1970's. I thought we were liberal. I think the spouse's Republican roots were dormant. Once he hit his 60's he became more conservative. It doesn't help that he listens to Republican propaganda on the radio...and actually believes that FOX News is a legitimate news source.
I'm not looking forward to the presidential election. There will be many months of bickering, but at least the spouse won't be driving my car. I'll have a Hillary bumper sticker and the spouse wouldn't want anyone to think he was a supporter!
