Nonsense.
The decision won’t come until after the election—the campaign issue ought to be framed by Trump to support a new health care program that affords people the option of buying various kinds of support as they see fit.
Pre-existing conditions? We don’t know what that really costs—in the present environment of continuing coverage, maybe not a lot; if necessary, some additional funding paid for by a surcharge on other health care requirement could be considered. One way or another, a public commitment to provide a backup funding system is part of the political debate.
Trump should fire Barr immediately. At a minimum, he should tell Barr that he is going to get fired unless he produces a reasonable explanation for having failed to charge McCabe or a clear indication that they have turned McCabe.
Barr is going to stand on prosecution of the bad guys until after the election assuming that Trump is going to be replaced by a Dem who will dictate that the effort is to be abandoned. We need a real Attorney General to replace Barr who will pursue the criminal conduct of the people involved.
He can't get anybody better confirmed by this Senate. Maybe he could recess-appoint a better candidate, but all of that candidate's actions would just be reversed by his Senate-approved successor.
