POLITICO’s Morning Score blog reported Tuesday that the National Federation of Independent Businesses will kick off a $2 million campaign to bolster the group’s endorsed congressional candidates. 

The campaign will include ads hitting U.S. Rep. Mike Michaud, D-Maine, in an effort to boost his Republican opponent Kevin Raye, according to the report. Raye, the current state Senate president, is also a member of the NFIB. 

The ad buy is targeting eight congressional districts. The NFIB, considered one of the leading lobbying groups for small businesses, is expected to announce its slate of endorsements soon.
