Steve King should go back to where he came from.

The Republican congressman from western Iowa would do the country a great service if he left Congress, since he apparently doesn't know how to stop talking. Speaking on Wednesday about Alabama’s abortion ban, which makes no exceptions for rape and incest, King argued that rape and incest made the world what it is today. And ... what, that’s somehow supposed to make them a good thing?

"What if we went back through all the family trees and just pulled out anyone who was a product of rape or incest?" King said. "Would there be any population of the world left if we did that? Considering all the wars and all the rapes and pillages that happened throughout all these different nations, I know that I can't say that I was not a part of a product of that."

Ersatz history lessons aside, as my colleague Kaylee McGhee wrote, “Steve King's rhetorical stupidity hurts the pro-life movement.” He’s no gaffe machine; he’s just dumb. And he harms the causes he pretends to support.

Both sides of the aisle joined in denouncing King, whose only contribution to society has been uniting the Left and Right in mutual condemnation against him.

Democratic Sen. Kirsten Gillibrand, who has positioned herself as the most feminist candidate gunning for the White House in 2020, opposes abortion restrictions. But thanks to King’s stupidity, that’s not the only reason she had to condemn him.

“You are a disgrace,” she tweeted Wednesday afternoon. “Resign.”

Sen. Bernie Sanders of Vermont chimed in less than two hours later: “Steve King is a racist, a misogynist and a disgrace to the country. He should not be a member of the United States Congress.”

For years, King has been cozying up to white supremacists and making bigoted comments about immigrants. As my colleague Quin Hillyer wrote this spring, after King compared his suffering to that of Jesus: “He’s a pathetic figure and an embarrassment to Congress. He should resign.”

The Right and Left can agree on few things these days, but here’s one: King should resign from Congress. If both sides continue to condemn him, they may be able to make that happen.
