Yes. It has been exceptionally bad today. Buzbee has wasted a TON of the prosecutions time making silly objections and shockingly getting a ton of them sustained. There were several times witnesses haven't even been able to testify to simple things occurring in their daily activities that are highly relevant. If they weren't so damaging, Buzbee wouldn't be going so hard to keep them out. Pretty much every witness so far is in Paxton's corner on a personal level, they're just being compelled to testify and aren't willing to lie under oath. I mean, shit, the guy today admitted that Paxton is basically a father to him, and that's the guy who Buzbee railroaded with objections the most.
There's damn good reason for the rules of evidence in trials. But this isn't a real trial, and those justifications largely don't exist here. The time limits are a real problem in that regard. If this were a criminal trial, the defense and prosecution would generally have the right to call all these separate people to testify (which would take away the hearsay issue), but that's not permissible here. Because of that, the general rules on hearsay should've been broadened significantly. Honestly, most of these people already sort of know each other. If not directly, then they know someone who does. They can assess credibility a lot better than normal jurors hearing testimony from perfect strangers. They also understand the inner-workings of most of these offices, so they should be given broader leeway in that regard as well.
In the end, this trial is for the public (and to provide cover for a few senators). Every senator knew how they were going to vote, whether that be: 1) guilty, no matter what, 2) not guilty, no matter what, or 3) let's see if the public comes out strong in Paxton's favor, and if not, then it's safe for me to vote guilty.
Buzbee is doing a good job keeping out a lot of really bad looking stuff, but the prosecution has been able to get in a lot in spite of that. With the empty grandstands, the lack of protests, and the lack of support from many other high ranking Republican officials, I think any Senator that went in under the 3rd option should be feeling confident that they won't get meaningful backlash from their constituents. Honestly, they can probably spin it as an advantage, both locally and nationally, claiming that they're now the party of accountability and rule of law. "Hey, forget everything we've done as a party up to this point, we just impeached a highly popular Republican in deep red Texas. We do what's right, regardless of political affiliation!" They're gonna say that either way, just based on the fact they voted to impeach him, but a conviction makes it a much stronger argument since they've spent these past few days/weeks/years arguing that the impeachment is just another liberal witch hunt.
