MSNBC's Joe Scarborough made headlines last week when the former GOP congressman announced he was leaving the Republican party. On Monday, he delivered a scathing op-ed in the Washington Post elaborating on why, with President Trump a prime target.

In tandem with Trump, however, are Republican leaders who continue to stand by him as he embraces "autocratic thugs," denounces the free press in ways that would make Stalin and Mao proud, and questions the bedrock principles of American checks and balances, writes Scarborough.

And where is the GOP outrage over his campaign's dealings with Russia? The party is "dying," complains Scarborough, and he writes that he can no longer defend it.



"Trump’s Republicans have devolved into a party without a cause, dominated by a leader hopelessly ill-informed about the basics of conservatism, US history, and the Constitution," he writes.

With control of the White House and both houses of Congress, the GOP had a real chance this year to redeem itself, but has failed spectacularly.

"The wreckage visited of this man will break the Republican Party into pieces—and lead to the election of independent thinkers no longer tethered to the tired dogmas of the polarized past," he writes.

At that point, "the two-party duopoly that has strangled American politics for almost two centuries will finally come to an end. And Washington just may begin to work again." Click for his full column.
