If I were President Trump, Id be passing the word quietly to dem senators in red states that if they dont want to be severely testored, they better give his nominee to the Supreme Court a favorable vote before October 1.
I can envision a whole lot of Great Falls, MT types of campaign appearances between the vote and election day if the nominee goes down because of purely partisan politics....And not just in red and purple states.
You might be on to something. That Montana rally might well have been designed to be a warning shot to those dems who are vulnerable in the November election.
