If Romney was elected President and did far-left junk, Republican AND Democratic members of Congress would sign onto it.
THAT is the danger.
I don't think so, but its possible. Remember how House Repubs voted against immigration reform and TARP under Bush. They are more conservative as a group this time around.
I'm going to be optimistic that if Romney gets the Presidency, he will do a good job. Only God knows though.
However,I cringe at the thought of another four years of Obama...
