Get ready for an ugly and sad political spectacle

The speaker of the U.S. House of Representatives has seen and heard enough.

Nancy Pelosi, who had dug in hard against impeaching Donald J. Trump, has changed course. She has announced a formal “impeachment inquiry” based on allegations that Trump has pressured the president of Ukraine to find dirt that would damage a potential political opponent, former Vice President Joe Biden.

So … there you have it.

Pelosi has contended that if the allegations are true the president of the United States has enlisted the help of a foreign government to bring down the candidacy of someone who might run against him next year.

This where it gets ugly in the extreme, ladies and gentlemen.

Congressional Democrats are talking about their “sadness” as they proceed toward formal impeachment. Are they crying crocodile tears? I am going to give them the benefit of the doubt.

The allegations against Trump now have been brought into the sharpest focus yet. Trump has acknowledged talking to the Ukrainian president about Biden and his son, Hunter, whose business dealings in Ukraine have become part of the story. He says he will release the transcript of a single phone call he had with the Ukrainians.

Is that enough? Hardly.

We need to hear from the whistleblower who revealed all this alleged behavior in the first place. This person reportedly witnessed a sequence of events that could blow Trump’s presidency straight out of the water. The word today is that the whistleblower will reveal himself or herself perhaps as early as this week.

That individual needs to tell the nation what he or she saw or heard from ringside.

Nearly three-fourths of the House Democratic caucus have endorsed the impeachment of Donald Trump. What we do not yet know is whether any Republicans will join them. Has the GOP House minority had enough as well?

No matter how all this ends up, with an impeachment or the House choking at the climactic moment, it will not end well no matter who is able to declare some semblance of victory.

We are moving — perhaps hurtling — toward an ugly chapter in a sad political story.
