The GOP has become dangerously radical since Obama has been president. It seems that having a Black man in the White House has, literally, driven many radical conservatives over the edge, and when we add the fact that they realize that the demographics are against them and growing worse with every day that passes, they've become not only dangerously radical, but desperate, without limits (as clearly demonstrated by the Republican 47 treason letter), and well financed, and that doesn't bode well for America.
A graphic example example of just how far over the edge the GOP has slipped can be seen in a quote by a radical conservative retired general. Retired army general, and FOX News analyst , Paul Vallely, is quoted as telling the Arizona Tea Party Patriots, "I had a call this afternoon from Idaho. The gentleman said, ‘If I give you 250,000 Marines to go to Washington, will you lead them?’" Vallely said as the group laughed and gasped. "I said, ‘Yes, I will, I’ll surround the White House and I’ll surround the Capitol building, but it’s going to take physical presence to do things" (http://thinkprogress.org/security/2014/01/28/3213361/retired-army-genera...).
