The problem lies less with Republican politicians than with everyday conservatives who pay thousands to left wing universities to brainwash their kids, and who spend millions collectively on left wing entertainment, who watch left wing television and left wing news.
Secondly, there is no offensive measures taken by conservatives. Why is there no conservative alternative to Big Entertainment? It would seem that there is a huge market being neglected. The 1988 discovery through Rush Limbaugh going nation-wide, was the enormous market for conservative news. Surely there must be the same for entertainment. Huge slices of the electorate get their "news" from entertainment. Why not compete to get the message through?
