The bona fides of the authors are pretty compelling, and their arguments are somewhat grounded.
I say somewhat, because they talk about “rules” for impeachment, not as written, of course, but just what they said happened in the 3 other times: Johnson, Nixon and Clinton.
Johnson did have a full House vote just to start the inquiries and draw up the articles of impeachment. Nixon had a House vote too, but a lot of investigation went on before the hearings took place. Clinton the same. As a matter of fact, Clinton was investigated for 6 years about real estate and sex harassment before he lied under oath about adultery. Talk about trying to turn over not one, but two legal elections. And the various stages and permutations of Ken Staars investigation was daily fodder on the nightly news.
And, of course, the Benghazi investigations (6, 7 or 8, I can’t recall) were certainly packed with closed hearings before Clinton was called.
So I think that argument of being not done according to the Marquis of Queensbury rules is a bit specious. Especially when the Democrats say that all this information will come out and the hearings public in a few weeks. I know that the complaint is that leaks are hurting the president. (What else is new? His own staff has been a flood of leaks since the inauguration.) But the more damaging ones, like Taylor’s, was his opening statement which he himself handed to the press. Wall Street Journal I think.
Similarly, the examples of past presidents using aid for leverage were pretty much all in the national interest such as regards to war, human rights, etc. I don’t believe Trump even had Ukraine on the radar until Biden became a serious contender.
Anyway, I toss out this link as an example of at least looking seriously at arguments from right wing thinkers rather than those who stormed the hearings the other day. BTW, a bunch of those guys were on the committees themselves and questioning the witnesses.
And I know I am no legal scholar. But then to the best of my knowledge, no one else commenting is either. We are all in the shallow end of the pool.
