I disagree with you Matthew. While the RINOs would like to discredit real Tea party candidates, so do Democrats. Hughes admits that many RINOs are disguising themselves in Tea party clothing, only to turn their back on voters after winning the election. And she advocates the right approach - examine their record, not their rhetoric.
If the Democrats want to spend money on real Tea Party candidates, I hope they spend all they have. If they spend it on saboteurs, the sabotur's record will give them away. Even if they beat a RINO and lose in the primary, we're better off: Democrats get the blame, the RNC learns that forcing a RINO on us will lead to defeat, and we'd get the same policies with a RINO as a Democrat.
