I agree. The time to vote against rinos is in the primary elections. A republican majority in the house and senate will be a tremendous advantage—even if some of them are rinos—(hopefully much fewer in number than in the past). In the general election you can't sit it out just because the candidate of your party isn't everything you want him to be. Still be a hell of a lot better than a democrat in the seat.
I live near Chicago. When I vote, if I think that the U.S. Senate race will be close, I’ll vote for Rep. Kirk (my congressman), since I don’t want to help split the anti-Democrat vote, helping the Democrat win with 49% of the vote. If I think that the race won’t be close, I’ll vote for Labno.
