This is what Biden said in full:
By the way, they talk about this great recession like it fell out of the sky – like, ‘Oh my goodness, where did it come from?’ It came from this man voting to put two wars on a credit card, at the same time, put a prescription drug plan on the credit card, a trillion dollar tax cut for the very wealthy. I was there, I voted against them. I said, no, we can’t afford that.
Leftists can quibble that he didn’t “lie” exactly, if you apply “I voted against them” ONLY to the last clause about tax cuts.
People with functioning brain cells can tell that’s a bunch of baloney. His statement obviously means:
Ryan voted FOR two wars, a prescription drug plan and a tax cut. I voted AGAINST them all.
But the record shows that he did vote for the two wars and the prescription drug plan.
As for the last one, while it is true he voted against it, the record shows he was foolish to do so.
