Here is another view, from Heather Cox Richardson, an historian who has a sizable following on FB. It proposes a theory for why the Dems abandoned witnesses for pretty simple, practical reasons.
“…Trump’s lawyers proceeded in the impeachment trial with the same rhetorical technique Trump and his supporters use: they flat-out lied. Clearly, they were not trying to get at the truth but were instead trying to create sound bites for right-wing media, the same way Trump and the rest of his cabal convinced supporters of the big lie that he had won, rather than lost, the 2020 election. In that case, they lied consistently in front of the media, but could not make anything stick in a courtroom, where there are penalties for not telling the truth.
In the first impeachment hearings, Trump supporters did the same thing, shouting and lying to create sound bites, and while the sworn testimony was crystal clear, their antics left many Americans convinced not of the facts but that then-President Trump was being persecuted by Democrats who were trying to protect Hunter Biden. So, while it’s reasonable to imagine that witnesses would illustrate Trump’s depravity, it seems entirely likely that, as Trump’s lawyers continued simply to lie and their lies got spread through right-wing media as truth, Americans would have learned the opposite of what they should have.
Instead, the issue of Trump’s guilt on January 6 will play out in a courtroom, where there are actual rules about telling the truth. Trump’s own lawyers suggested he should answer for his actions in a court of law, and in a fiery speech after the vote, Senate Minority Leader Mitch McConnell set up the same idea. But even if that does not happen, the Capitol rioters will be in court, keeping in front of Americans both the horrific events of January 6 and their contention that they showed up to fight because their president asked them to.
The constant refrain of the January 6 insurrection mirrors the Republicans’ use of sham investigations to convince people that Democrats are criminals—think, for example, of former Secretary of State Hillary Clinton’s emails—except, this time, the cases are real. This should address the problem of manufactured sound bites, and should benefit the Democrats with voters, especially as Republicans are now openly the Party of Trump.
McConnell tried to address the party’s capitulation immediately after the vote with a speech blaming Trump for the insurrection and saying that his own vote to acquit was because he does not think the Senate can try a former president. This is posturing, of course; McConnell made sure the Senate did not take up the House’s article of impeachment while Trump was still in office, and now says that, because it did not do so, it does not have jurisdiction.
McConnell is trying to have it both ways. He has made it clear he wants to free the Republican Party from its thralldom to Trump, and he needs to do so in order to regain both voters and the major donors who have distanced themselves from party members who support the big lie. But he needs to keep Trump voters in the party. So he has bowed to the Trump wing in the short term, hoping to retain its goodwill, and then, immediately after the vote, gave a speech condemning Trump to reassure donors that he and the party are still sane. He likely hopes that, as the months go by and the Republicans block President Biden’s plans, alienated voters and donors will come back around to the party. From this perspective, the seven Republican votes to convict Trump provide excellent cover.
It’s a cynical strategy and probably the best he can do, but it’s a long shot that it alone will enable the Republicans to regain control of the House and the Senate in 2022. For that, the Republicans need to get rid of Democratic votes….”
