That all makes sense, but even in cases where the Republican Party has control I don't see any "chipping away" going on.
The ObamaCare/budget debacle of late 2013 -- when Ted Cruz stood up with his infamous filibuster in the U.S. Senate, only to be roundly criticized by other Republicans -- spoke volumes about what we're up against in terms of dealing with traitors within the GOP.
I think we need to look to what’s happening in England with UKIP. It takes a charismatic leader, like Nigel Farange, to get such a movement going.
Farange could have tried to do what he is doing within the Conservative Party, but it wasn’t going to happen.
WE are the ones who have to chip away. The GOP leadership won’t do it, in fact it is they who have to be chipped away first, and the time for doing so is during the Primary season ala Eric Cantor, not the General Election.
