The woman starring in a new television advertisement that was set to air in Alaska on Wednesday -- and funded by Koch brothers-backed group Americans for Prosperity -- attacks the Affordable Care Act and Alaska Sen. Mark Begich in one breath.

In the ad, a woman addresses viewers from a sophisticated kitchen adorned with white cabinets. "I trusted the President and Sen. Begich. Lots of promises were made to pass Obamacare," she says.

Criticizing Begich's support of the ACA, she asks, "How can I ever trust him again? It just isn't fair. Alaska deserves better."

But the woman who laments her inability to trust the state's lone Democratic senator is not an Alaskan voter, as the ad seems to imply. The woman is actually an actress from Maryland. Actors are often used in political ads. But it's a tactic Begich's campaign is calling deceptive.

"Today's misleading ad from the Koch brothers is just more evidence that even billions of dollars can't buy integrity," wrote Begich campaign spokeswoman Rachel Barinbaum in an email.

The same actress has appeared in an advertisement promoting access to mammograms, which Barinbaum called "ironic," given the medical nature of that promotion.

The ad is the latest political foray into Alaska's health care reform debate by Americans for Prosperity. AFP is a national conservative group based in Arlington, Va., backed by billionaires David and Charles Koch, which seeks to influence elections and public policy across the country. The Alaska chapter defines itself as a "grassroots organization" on its Facebook page.

AFP is targeting three Senate Democrats up for re-election in 2014 that are viewed as the most vulnerable, according to the New York Times: Sen. Begich, Kay Hagan of North Carolina and Mary L. Landrieu of Louisiana.

President of AFP Tim Phillips told the New York Times that the group wants to "make sure Obamacare is the No. 1 issue (voters) are thinking about."

From Nov. 20 to Nov. 29, Americans for Prosperity is spending $39,450 for advertisement slots with Alaska television station KTUU, according to documents from the Anchorage NBC affiliate.

The advertisements are targeted at women, and feature female narrators, as research has shown that women are more undecided than men about the ACA, the New York Times reports.

The new ad is the latest partisan attack on the Affordable Care Act in Alaska. As reported last week, two websites in Alaska with ties to national conservative groups are also hoping to steer Alaskans away from Obamacare.

The two sites -- Know the Facts Alaska and Don't Enroll Alaska -- use different tactics to arrive at the same piece of advice: Delay enrollment in Healthcare.gov. While Don't Enroll is obvious in its anti-Obamacare sentiment, Know the Facts operates under the guise of neutrality, but offers Alaskans misleading information on the law.

The sites have ties to the Foundation of Government Accountability, a conservative think tank. While AFP denies involvement in the websites, Know the Facts and AFP have promoted each other on their Facebook pages.
