Well, Trump definitely wants to "reform the judiciary" so he can pack it with friendly judges who will tickle his sac while hammering his enemies. He couldn't give less of a shit about abortion law or any of that.
The rest of the party, though, cares very deeply about abortion law, and election law, and corporate law, and anything else that will get them elected, keep them elected, and make them all wealthy and powerful beyond their wildest dreams.
There are still a boatload of Dem-appointed liberal judges they would like to run off the bench and replace with hacks who graduated law from Tier 5 safety schools, a situation they covet that has nothing to do with Trump's interests, at least not directly.
Get the right judges on the bench, and all of a sudden those voter fraud lawsuits are gonna start breaking their way.
