GOP: We have proof that something can be and not be at the same time.

GOP: First, let's assume a GOP candidate cannot waffle or tell a lie. (Snort, snort...oh, sorry.)

George Bush said,"read my lips" about no new taxes and then had them raised.

Mitt Romney had mandatory health coverage is his home state and now condems Obama for the same  thing.

But they cannot lie or waffle, so logic dictates that contradictory things can exist at the same time.
