Tell that to my wife... I have a closet full of them and wore them long before Santorum ran for president. They work well during seasons when it's too cold not to wear some kind of sweater but not yet cold enough for a winter coat or heavy sweater.
But then again, I live in the Missouri Ozarks where some people wonder why I wear a tie. My usual answer is I'd look silly if I tried to drive around in a pickup truck wearing jeans and farm boots. I'm not a farmer and trying to look like one would be stupid.
If the worst thing people can say about a politician is they don't like his sweaters, I think he's doing pretty well.
Ha ha! Okay, I give! Wear the sweater vest with pride, FRiend!
