Rush picked the best of what he had to choose from. While I agree it makes the “RINO” charge pretty stupid, I don’t think it means Limbaugh would pick Romney as his favorite conservative, if there were other real conservatives in the mix.
I don’t think he would be Rush’s ideal candidate either and he pretty much says that in the article. However, since FR has now switched to out and out slander as a fundraising tool, against a friend of mine, I had to point out that there are solid, high profile Conservatives out there who believe Romney to be one of them.
