I know from experience that political disagreements are common between families.
My Mom was a staunch Republican. My dad... a old school Southern democrat. Every election she'd go vote while she was at work. My dad would be tied up on the farm, and she'd cook a big dinner and have beer on ice when he came in. He'd down a few, eat a big dinner, and doze off.
She wouldn't wake him till the polls closed. He fell for it every election.
That’s beautiful.
