Democrats see Pryor as one of the more vulnerable candidates next year. Bloomberg guns group targets Pryor

New York City Mayor Michael Bloomberg’s gun control group is following through with its pledge to air ads against Arkansas Sen. Mark Pryor, whom Democrats see as one of their most vulnerable incumbents in a tough 2014 climate.

A source tracking media spending told POLITICO the group has bought $350,000 worth of broadcast and cable airtime starting Friday and running through June 6, a crushing amount in a state where ad time is fairly cheap.


The bulk of the spending is the first week of the buy, although more may be purchased in the coming days.

Democrats have been concerned about their members being hammered by Bloomberg’s group and other gun control activists after legislation backed by the White House to expand background checks, among other measures, failed in the Senate.

Bloomberg’s group is going after the “no” votes in both parties, having already aired ads against Senate Republicans like Arizona’s Jeff Flake.
