Rabidly opposed to status quo leadership, maybe?
I think it was in the 2008 debates when Gingrich spoke on how many politicians are not interested in fixing anything, they just want to "manage the decay." I thought he was absolutely right, and with the exception of Trump, Carson, and probably Cruz, that's exactly what this current crop is looking to do.
I find that notion unacceptable.
It is interesting that you mention Gingrich, because I favored him in 2012. I am convinced to this day that he would have won.
Unfortunately, he got destroyed in forums like this website for not passing the conservative purity test. Now, four years later, Trump is the antithesis of the conservative purity test. By most standards, he fails on every level. But I see many of the people who could not tolerate the mention of the name Gingrich are now all-in for Trump. Believe it or not, some of these same FReepers even talked about Gingrich's marital infidelities. It's bizarre to say the least.
