Yes, We have Ann Wagner, David Limbaugh, Kit Bond to name a few.
Your point is?
The Limbaugh name is a huge conflict of interest that would raise a lot of negative reaction.
Wagner would be acceptable but she won't run and I don't blame her. She is a shoe-in for the Congressional seat she is in and why would she risk that to run against a seasoned political pro where she will have a big fight ahead of her with no guarantees that she has if she stays where she is.
And no matter who would replace him the Dems will accuse him or her of being a stooge of the party bosses who overturned a valid primary election. Whatever would be gained would also be lost.
