So U.S. Attorney General Robert Barr was testifying the other day in front of a U.S. Senate panel.

During that testimony he said, “I think spying did occur” against the Trump campaign. He also suggested the origins of the Russian investigation may have been mishandled.

That’s not shocking.

I mean, we know that the Democratic National Committee hired the opposition research firm Fusion GPS to dig up dirt on Trump.

We know that Fusion GPS?hired a former British spy who met with Russians to dig up that dirt. We know the British spy produced the now-infamous “Trump dossier” that was used to get Foreign Intelligence Surveillance Act warrants on Trump campaign officials.

(We also know that Hillary Clinton had classified material on a home-based email server and that her staff smashed phones with hammers, but that’s a whole other kettle of fish.)

If you’re a Democrat, you say, “So what?”

We also know that Trump was trying to build a tower in Moscow and offered up a sweet penthouse to Vladimir Putin.

We know at least 17 Trump associates had contacts with Russians or Wikileaks – not the least of which was the much-maligned Trump Tower meeting with Trump’s son-in-law and the Russian lawyer. We know Wikileaks released hacked documents during the campaign that made Hillary look bad.

We know Russians spread false stuff on social media to make Hillary look bad.

We know there were at least 100 face-to-face interactions, phone calls or electronic messages between Trump associates and Russians or Kremlin-linked figures.

And we know at least three Trump associates lied about those interactions.

If you’re a Republican, you say, “So what?”

Now, we know all this stuff is true about both 2016 campaigns. It’s factual. It’s not fake news.

Barr also told the senators that he would be releasing a redacted version of the Mueller report – the one that concluded there was no Russian collusion – sometime next week.

What’s interesting to me is how folks react to such things.

Democrat Speaker of the House Nancy Pelosi, talking about Barr, told the Associated Press, “He is not the attorney general of Donald Trump. He is the attorney general of the United States. I don’t trust Barr, I trust Mueller.”

She said she’s “very concerned” about Barr’s handling of Mueller’s report and accused Barr of being Trump’s flunky.

Then she said, “The fact is the president has engaged in activities that are unethical, un-American. ... In every way he is unfit to be the president of the United States.”

Frankly, she may be right about that. I don’t think you will find too many people – even the most ardent Trump supporters – who would argue that he is “presidential.”

But that brings me to my point – that the political divide is at its historic widest.

I am confident people on both sides of the 2016 campaign lied to Congress or lied to investigators or cheated on their taxes or failed to register as foreign agents or met with Russians or misused campaign funds or obstructed justice.

But if you’re a Republican, you look right past any wrongdoing on your side. You stomp your feet and yell, “Lock her up!”

Conversely, if you’re a Democrat, you look right past any wrongdoing on your side. You stomp your feet and yell, “Impeach 45.”

Republicans make excuses for all manner of reprehensible behavior by other Republicans. And Democrats make excuses for all manner of reprehensible behavior by other Democrats.

And through it all, one side or the other will wail and gnash their teeth and then – dramatic pause – no one will be held to account.

Hillary won’t be held to account. Trump won’t be held to account.

Democrats and Republicans have shown time and again that they will do virtually anything they can get away with to gain or retain power.

They’re too busy trying to undermine their counterparts to be overly concerned about crafting policies that we need to push this country forward.

It’s tragic.

Because in the final analysis, there’s a fair bit of equivalency here.

They’re all crooks.
