A good example of how to do it is Brad Wenstrup, a combat surgeon in Iraq and bright guy, upset Jean Schmidt in Ohio-2 district (Cincinnati and southwestern Ohio).
Brad is strictly Tea Party endorsed and votes the right way on veterans, guns, budget, foreign policy, pro-life, you name it.

Another is Ben Sasse from Nebraska soon to be the new Senator from Nebraska.This guy is a true leader.
