WASHINGTON — President Trump has made branding Democrats as out-of-the-mainstream, economy-wrecking socialists one of the centerpieces of his re-election strategy. He has sought to do so partly by making four junior Democratic members of Congress — all women of color who are on the left side of the party’s ideological spectrum — the faces of the party, and conflating their views with the Democrats seeking their party’s presidential nomination.

It is a message he has repeated with varying degrees of intensity and accuracy for weeks. And while a few of his fellow Republicans have expressed unease about how he has framed his scathing criticism of one of those four Democrats — Representative Ilhan Omar of Minnesota, who was born in Somalia and immigrated to the United States as a refugee — as a call for her to “go back” to her native country, Republicans have embraced the president’s broader efforts to cast Democrats as socialists.

How much truth is there to Mr. Trump’s characterization of the Democratic Party? Here is a fact check.

What Mr. Trump said

“A vote for any Democrat in 2020 is a vote for the rise of radical socialism and the destruction of the American dream.”

First things first: All Democrats are not socialists. Most Democrats are not socialists. Of the 24 candidates for president, only Senator Bernie Sanders of Vermont identifies himself as a democratic socialist. (Representative Alexandria Ocasio-Cortez of New York, one of the four House members the president has taken to trashing, rose to fame after running on a democratic socialist platform.)
