Republican Cory Gardner is up with his first TV ad in his race against Rep. Betsy Markey (D-Colo.), and he's going after the incumbent right out of the gate. 

The ad takes aim at Markey's voting record, highlighting her yes votes on healthcare reform and cap-and-trade.

"We sent her to Congress to fight for us," the ad's narrator says. "Instead, Betsy Markey has hurt Colorado with one bad vote after another. Markey voted for Obama's takeover of our healthcare system, co-sponsored the law to take away a worker's right to a secret ballot. She even voted for cap-and-trade that could cost 35,000 Colorado jobs." 

New numbers out Wednesday from The Hill/ANGA midterm poll show Gardner with an edge. Markey trails by just three points — 44 percent to 41, with 14 percent of likely voters undecided.

The poll offers some hope for Markey, as the race is within the margin of error. She has 89 percent support among Democrats and is winning independents at 43 percent to Gardner’s 39. She even has a decent amount of Republican support, at 11 percent.
