A political committee backed by the billionaire GOP donor Charles Koch announced Thursday that it’s launching a direct mail campaign supporting U.S. Rep. Ron DeSantis for Governor.

Freedom Partners Action Fund, a Washington-based super PAC, endorsed DeSantis in the Republican primary for Governor last week, promising to back up its words with mail campaigns and digital advertising.

“Ron DeSantis is a proven leader. As governor, he’ll continue to support policies that lift up Florida’s taxpayers and small businesses, and fight against giveaways to special interests at the expense of those who can least afford it,” said FPAF Director Nathan Nascimento.

To that end, FPAF said the mailers announced Thursday showcase DeSantis’ “commitment to growing Florida’s economy, supporting taxpayers and small businesses, and combating corporate welfare.”

The front of the mailers say the Republican congressman “will be a champion for taxpayers” in large print, adding that he will fight to “close special interest loopholes” and end “wasteful spending,” among other things.

The back of the mailers stick with the “champion for Florida taxpayers” language and also implore readers to cast their ballot for DeSantis in the Aug. 28 Republican primary.

FPAF said the mailers are going out statewide to a targeted set of voters. It added that more direct mail campaigns would follow.

DeSantis is running against Agriculture Commissioner Adam Putnam in the primary. Despite a large money lead and a big head start on the campaign trail, recent polls show DeSantis has soared to a double-digit lead in the GOP nominating contest.

Much of that edge can be attributed to President Donald Trump’s endorsement of DeSantis.

The most recent poll, which puts him up 50-30 over Putnam, found nearly two-thirds of likely Republican primary voters said they were more willing to vote for a candidate who had been endorsed by Trump.
