Well, I will readily admit that the Republicans aren't doing nearly as much as they could. That the Democrats can say what they do without getting laughed at is a case in point.
But the simple matter is that while the Democrats have put out one healthcare plan, the Republicans have put out three.
There is a saying that if you tell a lie often enough, people will believe it as true. The Democrats are telling lie after lie, but the Republicans aren't standing up to them.
