Conservatives Too Polarizing

Do you agree with Karl Rove that the TEA Party faction of Republicanism must be opposed and so-called "mainstream" GOP incumbents supported? I for one think this is one hundred and eighty degrees out of phase and that advocates of restraint including lower taxes, lower spending, and less government intrusion into our lives are the candidates that merit support. If Rove and his establishment backers win, I will no longer be able to consider myself a Republican.
