President Trump didn’t make an appearance at Nationals Park for Washington’s home opener Monday afternoon, but that didn’t mean politics stayed away.

Not long after the Nats finished off a 4-2 win over the visiting Marlins — even as most of the crowd of 42,744 flowed toward the exits — protesters hung a large “Impeach Trump” banner from the observation deck on the first base side.

“We waited until the game was finished to show our respect for opening day of America’s favorite national past-time, unlike Donald Trump who couldn’t be bothered to show up for a presidential tradition that lasted for a century until today,” one of the protesters, Jason Charter, wrote in an email Monday night.

(While many presidents have thrown out opening day first pitches, the tradition has flagged in recent years; Trump hardly broke a century-old tradition.)

“The banner that was unfurled after the game violates our guest conduct policy,” a team spokeswoman said in a statement. “It was promptly confiscated by security.”

Charter wrote that he and Ryan Clayton of Americans Take Action — who have executed similar stunts in recent months — simply walked in with the banner, and that its deployment lasted a few minutes and was met with cheers. The slogan was presented on a 27-by-21-foot Russian flag, and urged resistance.

“American Presidents for the last 100 years have thrown out the first pitch on baseball’s opening day, so it’s a significant day in both sports and politics,” Charter wrote. “Normally, the President has the common decency to celebrate this day with most Americans, but with a [low] approval rating, Donald Trump was apparently too scared to show his face for fear of being booed out of the stadium.”

“We dropped the ‘Impeach Trump #RESIST’ banner on baseball’s opening day because Donald Trump in the White House is a clear and present danger to the American people and the U.S. Constitution,” Clayton said in an e-mailed statement.

I guess some Nats fans don't want to make America great again. #resist
