Of course, all politicians lie. But I wonder of the two liars vying for the Presidency which is the biggest liar? Not surprising, to me at least, Romney.
According to PolitiFact, Obama's lying to some extent about 29% of the time, with 2% of his campaign's claims ranking as Pants on Fire. As for Romney, he's lying about 43% of the time, with 9% of this campaign's claims ranking as Pants on Fire.
They all lie, but Romney is the biggest liar.
