Elizabeth Warren needs to shake the rocks out of her noggin.

The Massachusetts senator and candidate for the Democratic presidential nomination thinks the House of Representatives needs to commence impeachment proceedings against Donald Trump now.

Don’t wait, she said. Do it now. Immediately if not sooner.

Warren is aghast at the dishonesty, duplicity, deception and dissembling that special counsel Robert Mueller revealed in the Trump administration. It all starts rotting at the top, according to Warren.

So, let’s get on with it, she said.

Wait a minute. I know Sen. Warren is aware of this, but impeaching a president carries a huge political gamble. Is she really saying that she believes the Senate would convict Donald Trump of unspecified “high crimes and misdemeanors” if the House actually were to impeach him? Let’s get real.

I, too, am flabbergasted by what Mueller has revealed in his 448-page report. He didn’t find evidence of collusion between the Trump campaign and Russian election hackers in 2016. He also declined to clear Trump of obstructing justice, saying Congress has the authority to act. Some of the language Mueller used in that report is scathing in its tone.

Let us face a hard reality, though, shall we?

The House can impeach with a simple majority. No sweat, given that Democrats now hold a comfortable majority in that chamber. But then the bar gets a whole lot higher in the Senate, which needs a two-thirds majority to convict the president of any impeachable offense. Republicans still hold a majority in the 100-seat Senate. Does anyone seriously believe that enough Republicans will abandon the president and join Democrats in convicting him? Pardon me while I laugh out loud.

House Democratic elders, led by Speaker Nancy Pelosi, understand the reality of impeaching this president. The House could approve articles of impeachment, but the current Senate isn’t going to finish the job.

The political recourse rests at the ballot box. It’s that simple. To send the president packing, Democrats have to nominate a candidate who can make the case that the nation deserves far better than it has gotten, according to Robert Mueller’s finding.

American voters will take care of the rest.
