"Want to go with"?
I think this is more midwest than ethnic based, although it could be originally driven by, say, Germans and then picked up by those of us who aren't. I used to think it was Chicago based, but it isn't. One of my housemates grew up in Iowa and MN, and she uses it too. Neither she nor I have any German ancestry.
There's no defense for it grammatically, but I can promise it's a hard one to break!
