Establishment GOP vs. grassroots: Civil war or growing pains?

Whenever I talk to my more moderate Republican friends (and I have many) about challenging incumbents their side of the conversation is always filled with the same excuses masquerading as reason.

“I have no problem with incumbents being challenged but this just isn’t the right time/challenger.”

And: “You (Tea Party people) just need to find better candidates.”

My only response to them now is, “How are you not at the point where you want to go out and find better candidates?!?!?!?”

If you can survey the political landscape in America for the past twenty years and are OK with at all that has gone on while Orrin Hatch, Mitch McConnell and the rest of the adults in the GOP have held sway in the party then you and I definitely have a problem.
