That's not measurable yet as far as Romney's effect on that race. Mourdock is not yet a household name in Indiana...that's why it is tied. I expect he will do fine...especially if people on here and elsewhere who waste time just being bitter about Romney would instead spend their time doing something positive for other candidates worth getting excited about like Mourdock and just ignore Romney one way or the other.
When Goldwater went down, so did a whole big bunch of other Republicans.
Running a candidate for President who is a natural born loser is simply stupid,.
