Regrettably, the GOP wants no part of true conservatives. Sen. Cruz won his seat in TX, despite the party clearly supporting his primary opponent (name not recalled). In fact, I'm convinced that many would rather work with Democrats than "Tea Party" conservatives.
If this country is to be saved, it will be by 1 of 2 methods:
1.) States like TX, AZ, OK, (I hope) MO, and others, with conservative leadership, says "hell no" to the federal gov't continued intrusions.
2.) Some key Congresspeople or Senators with conservative blood, flee the GOP in favor of the Constitution Party. The CP is unlikely to get main stream status on it's own. Not enough money, and too much opposition in the media and from both parties.
