I don't look for the GOP in Montana to take a spanking in the next election even though they could use a few whacks for the anti sportsman issues they are pushing.
The legislative session will be finished well over a year ahead of the 22 elections. Much of the loony toons that has happed will be forgotten and replaced by other issues with the vast majority of voters.
It is said that all elections are local, but I am not so sure that is true any more. With more and more voters getting there news from 24/7 cable news channels, Talk radio and big social media national issues have greater influence. With the democratic party in Washington being lead by 80 year old plus dinosaurs that are showing signs of senility and the squad getting all the headlines the issues are likely not going to be the ones democrats in Montana want to run on. Add in that the party in control of the white house historically does poorly in the midterm elections and it is likely that Montana's GOP has a good year in 2020.
