WASHINGTON — No sooner did Rep. Jeff Van Drew pledge his “undying support” to Donald Trump then he received support from one of the president’s political allies for his re-election.

Beginning this weekend, a pro-Trump political action committee, the Committee to Defend the President, will air $200,000 worth of television ads in Van Drew’s 2nd Congressional District, plus another $50,000 in digital ads.

Van Drew, elected in 2018 as a Democrat, has officially filed with the Federal Election Commission to run for re-election as a Republican. He announced Thursday at a White House meeting with Trump that he was switching parties.

The ad thanks Van Drew for voting against impeaching Trump — one of only three House Democrats to oppose any of the counts — and urges viewers to re-elect him.

“Anti-Trump Democrats have long claimed to put country before party, but only Van Drew has actually done so," said Ted Harvey, chairman of the Committee to Defend the President, who thanked him “for seeing reason and tuning out the charade of an impeachment process that has gone on far too long.” ”

The committee spent $4.2 million so far this year to support Trump for re-election, according to the Center for Responsive Politics. It began as the Stop Hillary PAC and spent $3.4 million in 2016 against the Democratic presidential nominee.

As a Democrat, Van Drew endorsed U.S. Sen. Cory Booker of New Jersey for president. Booker since has sent out an email to raise money for Van Drew’s eventual Democratic opponent.

The Democratic Congressional Campaign Committee, meanwhile, said Van Drew should return the small-dollar donations he received. However, just 5 percent of the money Van Drew has raised for his two congressional campaigns, however, came in amounts of $200 or less, Federal Election Commission reports show.

“Nurses, school teachers, and working class New Jerseyans sent Jeff Van Drew their hard-earned dollars when he opposed Donald Trump’s attacks on working families," DCCC Executive Director Lucinda Guinn said Friday. "Now that he’s traded in his values for a presidential endorsement, it’s time to give those folks a refund.”
