Democrats are back on the air in Arkansas, attacking Senate candidate Rep. Tom Cotton (R) as a "politician we just can't trust."
"The real Tom Cotton? Just scratch the surface," the ad's narrator says as Cotton's face is shown on a scratch-off lottery ticket. "Cotton made hundreds of thousands of dollars working for corporate interests. In Congress he takes their campaign cash, luxury trips around the country, and then backs their schemes: Privatizing social security, gambling it on Wall Street, pledging to keep tax breaks that ship jobs overseas. The real Tom Cotton? A politician we just can't trust."
Cotton and Sen. Mark Pryor (D-Ark.) are locked in a tough race in conservative Arkansas. Both sides have been spending heavily on TV ads for months. Polls show it's a close contest.
