We plowed this ground thoroughly yesterday, but add Politifact to the near-universal condemnation of Tom Cotton’s latest ad, blaming his vote against farm bill on President Obama.

The fact-checking operation gives Cotton its worst label — Pants on Fire.

Cotton said that Obama “hijacked the farm bill (and) turned it into a food stamp bill.” That’s not correct — food stamps have been part of every farm bill enacted since 1973. One could say that Cotton and his allies in the House, by seeking a farm bill stripped of food stamp provisions, were actually the ones taking a more radical step, one that Congress ultimately voted against. We rate this claim Pants on Fire.

Cotton is still running the ad. His people are touting it. Thus, the Arkansas Blog “shameless” award.
