The Service Employees International Union (SEIU) launched a new television ad Thursday blasting Nevada Republican Sharron Angle.

In the ad, Angle is criticized for her positions on abortion as well as Social Security. The ad shows women at various stages of life — from a child to an elderly person — and states that Angle's election to the Senate would leave them worse off.

"At every stage, it would be worse for her — for all of us. Sharron Angle: too dangerous to have real power over real people," concludes the ad. 

Angle is challenging Senate Majority Leader Harry Reid (Nev.).

The ad started running Thursday and is slated to air until the day before the election, Nov. 1. The ad buy costs $225,000, according to a union official.

SEIU has invested significant resources in protecting Reid this election. They have mobilized their union members in support of the top Senate Democrat and have made a $500,000 contribution to the Patriot Majority Fund, a 527 group that is doing field and media work in Nevada.

Despite vast support across the labor movement, Reid still finds himself in a very competitive race with Angle. The GOP challenger has been helped by outside campaign spending as well, with groups going after the Senate leader for his role in pushing through the Democratic agenda this Congress.
