Among the Tea Party and the hardcore GOP base, though, it seems as though impeachment is well on the way to becoming yet another one of those articles of faith, right along with absolute belief in the fact that Fast & Furious, Benghazi, and the IRS targeting story are the worst Presidential scandals in American history. In fact, notwithstanding the fact that the leadership opposes impeachment and knows that it would be a political disaster, it remains to be seen whether this impeachment talk remains something confined to the fringe of the GOP and the conservative or if it starts to become a more mainstream idea to the point where the leadership in Congress finds itself forced to “do something” in response to pressure from the base. That pressure could increase if the GOP captures the Senate in November and the base of the party finds itself energized in the manner it was after the 2010 midterms. It could also become an issue if and when the lawsuit that the House of Representatives intends to file against the President ends up going nowhere, as I fully expect that it will.
It will. Expect the last two years to be nothing but chaos. Your semi-regular reminder: for all the damage that Republicans did to their "brand" in 1998, two years later Bush was President, and then two years after that, he allowed 9/11 to happen on his watch and America rewarded the GOP with total control of the government for 4 years, which led to the financial crisis of 2007-2008.
Republicans didn't exactly lose when they impeached Clinton. They won, and handily.
