WASHINGTON — Americans for Prosperity, the political group backed by the billionaire brothers Charles and David Koch, is targeting three of the most vulnerable Senate Democrats who are up for re-election next year. The group’s efforts are part of a new $3.5 million attack advertising campaign that hammers lawmakers for supporting President Obama’s health care law.
The senators — Mark Begich of Alaska, Kay Hagan of North Carolina and Mary L. Landrieu of Louisiana — are all from conservative-leaning states that voted to elect Mitt Romney in 2012. The ads will start running in those states on Wednesday.
Americans for Prosperity is also targeting three Democratic members of the House who are in danger of losing next year: Ron Barber of Arizona, Joe Garcia of Florida and Patrick Murphy, also of Florida.
