President Trump resorted to one of his favorite pastimes — insulting women — making a sexist comment about Meghan Markle … all because she dared to encourage Americans to vote.

Meghan and Prince Harry have not officially endorsed any political candidates … but the couple recently entered the convo by urging folks to cast their vote in November, which the Duchess of Sussex calls … “the most important election of our lifetime.”

Trump was asked about this at his Wednesday press briefing by a reporter who framed it as Meghan’s words being an endorsement of Joe Biden … and he did not respond kindly.

The Prez said, “I’m not a fan of hers,” adding, “I wish a lot of luck to Harry, ’cause he’s gonna need it.”

By the way, if you’re wondering why most people presume the Duke and Duchess are anti-Trump, Harry said … “As we approach this November, it’s vital that we reject hate speech, misinformation and online negativity.”
