When people say that Democrats should unify, the part they leave out is most important: Around what? Nearly everyone in Washington seems to assume that progressives should shut up, accept their place, and unify around the status quo.

Think about what an arrogant and preposterous request that is. Progressive leaders, including our representatives in Congress, should abandon all of our policy positions and sell out our voters to please the Democratic establishment. Saying “hell no” to that would be an enormous understatement.

If Democratic leaders don’t want to fight Donald Trump, that’s their problem, not ours. We signed up to rout him and send him home. If you’re not on board with that, get out of the way and let us do it. Democratic voters were clear in 2018 that they want Mr. Trump impeached. Yet again last week Speaker Nancy Pelosi and her allies blocked an opportunity by tabling Rep. Al Green’s resolution.

Unlike Mr. Green, I don’t think we need to discuss President Trump’s political or racial ideology to favor impeachment. The president has clearly committed two crimes. Robert Mueller’s report outlines double-digit instances of obstruction of justice. That’s a felony. Michael Cohen confirmed that Mr. Trump worked with him to pay hush money to Stormy Daniels in violation of campaign-finance laws—a crime for which Mr. Cohen is in prison.

That’s apparently still not enough for Mrs. Pelosi. There is not a single public official doing more to protect Mr. Trump than she is. Even Attorney General William Barr couldn’t stop an impeachment inquiry if he tried. The only person who has the power to seek justice against Mr. Trump steadfastly refuses to pursue him. The only thing Mrs. Pelosi appears to be resisting is holding Mr. Trump accountable.
