Looks like Montana has been Californicated.
You also have the power of incumbency at work.
To me, the excessive number of 1% races are a priori evidence of active vote fraud operations. Be nice if we had a real Attorney General in place to find out.
My sister lived in Montana for several years and it changed quite a bit. Maybe an influx of libs was why.
California has nothing to do with this. It is a crappy excuse. Montana has elected 50 out of 52 Democrat Senators. It would be an exception to the rule to elect Rosendale.
