The Rats aren't persecuting Trump because they want him to be the nominee. They are going after him because they don't want him elected.
I think there are some of both among the Dems - and it may be all mixed in there. The dream scenario for them is that he is the nominee, or at least has the highest delegate count before the official vote at the Convention, but then gets convicted. Even if a conviction doesn't bar him from running, it likely makes him unelectable. I don't think many of them would be happy if he dropped out tomorrow because that would give Republicans a better chance to nominate a more electable candidate.
The absolute best way to fight the totalitarian state telling us who we can elect is to elect the person they are persecuting.
I disagree. That's "sending a message", but it isn't actually fighting anything. I mean, if the guy they're persecuting is an ineffective buffoon (whether or not you see Trump that way), is electing him really smart? Remember Rob Blagojevich? He was that idiot populist governor of Illinois that eventually got convicted of corruption but arguably was targeted unfairly. Should they have re-elected a moron just because he was treated unfairly?
The best way to fight them is to whomever will do the best job while in office to dismantle/counter the totalitarian state. And that may well be someone other than one of the guys being persecuted.
BTW, I sure don't see the Pub establishment doing anything meaningful to end the two tiered justice system that exists today, or the persecution of Trump.
Exactly what do you expect them to do, other than to try to elect good judges on the state level, and try to appoint the right folks to the federal bench? The truth is that there really isn't anything the GOP could have done with those New York prosecutions. It was in a Dem area, with a Dem judge and a Dem prosecutor. How does the GOP "end" anything there?
