Cantor's mistake was in using the trashing of the grassroots, as his strategy, instead of challenging the dems! Imo, the institutionalized-Rs BELIEVED the ultra-liberal msm's talking points that 1. The TEA party, as a movement, was dead. And, 2. The INDependents want more govt expansion and intrusion. Then there's #3: The majority of AMERICAN Citizens, w/hispanic roots, DO NOT WANT "amnesty"; nor do they (ME included!) approve of the exploitation, and the pandering, of illegal aliens!
There's also a #4. And that one is where the msm puts the fear-of-God in ALL those that even mention the repeal of the "affordable" Care Act (aka Obamacare). Like "global warming" (aka "climate change"), the dems, in unison w/ the global liberal msm, continue working overtime trying to sell the FAILED "It's a settled-science." narrative. As it really isn't at all!
As long as there are CORRUPT FOOLS, in the GOP, that continue to want to TRY to "play with" the socialists and progressives of the Democrat Party -- instead of standing FOR the Constitution, ltd govt, and States rights, we, as a nation, WILL continue to fall, economically AND morally. At that rate, eventually collapsing and finally becoming that "3rd world" banana-govt, that has a politically-impotent military; and a "kangaroo-court".
Obama's "fundamental transformation", and Cloward & Piven's wet dream of "Overwhelming the system", will be complete. THIS is what Rush Limbaugh wanted to "fail"!
