Greg Sargent makes some good points:

President Trump’s explicitly stated position on the Ukraine scandal is that there was nothing whatsoever wrong with the conduct detailed in the White House summary of his call with Ukrainian President Volodymyr Zelensky.

What Trump needs right now is for as many Republicans as possible to voice this position as well. He needs them to also state unequivocally that there was nothing whatsoever wrong with that conduct, as opposed to merely attacking Democrats and the process.

Yet two new revelations underscore why this will only grow harder for Republicans: A diplomat will testify to new details about the freeze in military aid to Ukraine, and it’s now clear the “transcript” of Trump’s call is incomplete. Both will worsen the basic dynamic for Trump.

There are some, like Senator Rob Portman of Ohio, who are acknowledging that what the president did is deeply wrong but still insisting that it doesn’t rise to an impeachable offense. That’s earning Portman some blistering criticism. It doesn’t seem like a great piece of turf on which to stake your tent if you’re looking for safety.

Honestly, though, that is about the best the Republicans can do. Outside of some Freedom Caucus sycophants, GOP lawmakers are simply not going to parrot the line that the call was “perfect” or that the president’s conduct more generally was acceptable.

It would help them help the president if Trump would admit an error in judgment. It may infuriate most of the country, but it’s still a tenable position to argue that with an election so close at hand, it would be best to let the voters decide Trump’s fate.

That’s hard to do if it’s not the official line coming out of the White House. At some point in the near future, I think this may become an unbearable problem for many Republicans who want to either vote against impeachment or acquit him of the charges after a Senate trial.

The call with the Ukrainian president seems unlikely to remain as the main focus of the probe or the charges. We’ll be looking much more at what preceded the call and the actions of Rudy Giuliani and his Ukranian thugs. This really is the biggest scandal in American history, and the phone call is the least of it. I believe the hearings and the trial will bring this out and make it excruciating for anyone to argue that the behavior merits a mere slap on the hand.

People like Senator Portman who have staked out a middle ground will see the ground shift beneath them. He’ll be looking for a safe place, but he won’t find one. If he could argue that the president has acknowledged his error and is remorseful, it would perhaps give him a new piece of turf. But the chances of that happening are almost nil.

I continue to think that Trump’s own character and personality are the reasons he may actually get removed from office.
