The vast majority of the public that could not care less about politics and will consequently never notice lies nor exposure.

The last group will hear about both over the watercooler, but probably conclude it is just the left and right trading hyperbolic accusations again. Republicans seemingly CANNOT stop telling lies about Dems, whose sole hope is thus to keep telling the truth about them and pray people listen: Two party addition by subtraction.
