Or that an increasing drumbeat of propaganda will culminate in the American equivalent of the Reichstag fire. Or even in the "assassination" of a secondary Democrat official -- creating a "martyr for the cause".
There are people on the left who would do the deed (think ACORN) and people in the White House who would give the order (think Emanuel/Axelrod).
These people aren't going to let the Tea Parties interfere with their plans.
It's not over...
Right now, I think their biggest liability, and their greatest potential asset as a "martyr for the cause" is not so secondary.
