Very quickly. Within 24 hours. Didn’t even wait to see who else was running.

The press release…

Citizens United Political Victory Fund (CUPVF), the affiliated PAC of Citizens United, is proud to announce its endorsement of Congressman John Fleming for the open U.S. Senate seat in Louisiana today.

“Louisianans deserve a trusted conservative in the United States Senate who will put the priorities of the people of Louisiana first and Congressman John Fleming is that trusted conservative,” said David N. Bossie, President of Citizens United.

“Dr. Fleming has been a conservative change agent in the United States House of Representatives leading principled fights against former Speaker John Boehner’s big spending Obama-lite policies. Congressman Boustany on the other hand, has been described by the highly-respected Almanac of American Politics as having a ‘close relationship with House Speaker John Boehner’ and having a voting record that is ‘relatively moderate for a Southern Republican’” Bossie continued.

“The contrast in this race could not be more clear. If you want a strong conservative leader who will stand up to Washington’s failed status quo and fight to make Washington work for the people of Louisiana, I urge all voters to support John Fleming in Louisiana’s primary election for the U.S. Senate in 2016,” Bossie concluded.

CUPVF has also contributed $5,000 to Dr. Fleming for the upcoming primary election.

CUPVF previously endorsed Former Congressman and now Attorney General-elect Jeff Landry against Charles Boustany in the 2012 congressional primary that was caused by redistricting for many of the same reasons.

It was a no-brainer that Citizens United wouldn’t be on Boustany’s side. They’ve been critics for a long time. What’s perhaps most interesting is the Fleming endorsement and how it forecloses on other potential candidates. Rob Maness, for example, would have really liked to get CUPVF on his side in advance of a run.

What else will be interesting is whether some of the other conservative groups out there get involved in the early stages of the race. The Senate Conservatives Fund, for example, and the Club For Growth have both played in Louisiana races. Both would appear friendly to Fleming, though whether they get in early the way Citizens United has is unknown.
