Republican Senate leader Mitch McConnell (R-Ky.) is pushing back on calls from within his party to impeach President Biden, saying it would be bad for the country.

The comments are not particularly surprising - McConnell is a cautious creature of the establishment who has made his differences with the Trump wing of the party quite clear.

The pro-Trump side of the GOP has long called for Biden to face impeachment, but momentum has been growing lately with a cascade of new evidence about Biden's corrupt role in his son's influence peddling and the efforts of the Justice Department to cover it all up.

McConnell says no!

Over in the House, Speaker Kevin McCarthy (R-Ca.) has begun speaking about an impeachment inquiry, although in cautious tones.

But McConnell told the New York Times that impeaching Biden would trivialize impeachment - a process that accelerated rapidly during the Trump presidency - and continue a vicious cycle of partisan retribution.

“I said two years ago, when we had not one but two impeachments, that once we go down this path it incentivizes the other side to do the same thing,” McConnell said.

“Impeachment ought to be rare,” he added. “This is not good for the country.”

Tit for tat

While one could admire McConnell's idealism - or is it cowardice? - Republicans have few good reasons to show restraint after the way Democrats treated President Trump.

Impeachment should be rare, but Dems already weaponized it by putting Trump, and the country, through not one, but two impeachment circuses. Oh, and there was that whole "Russian collusion" thing.

Of course, Democrats are now suddenly discovering their principles as they face the possibility of getting a taste of their own medicine.

“Instead of pursuing this shameless and baseless impeachment stunt, House Republicans and Speaker McCarthy should join the president to work on continuing to bring down inflation and lower costs, create jobs, and grow the economy,” White House spokesman Ian Sams said in a statement obtained by The Post.

The bottom line is that Democrats have already broken just about every "norm" there is - including, most recently and alarmingly, the one against jailing political opponents.

Is it possible to unite with an opposition this unscrupulous? It seems McConnell hasn't pondered the question.
