Ahh... Last line in the article... I see... Rosendale may also go after Testercle's seat. So Sheehy and Rosendale would be primary opponents for the seat... I get it.
Bridger... Yep, that's an east of the hump name... Billings/Bozeman area likely... So right in Testercle country. But what seems to be missing is 'farmer'. East of the hump the game is big oil vs. big farm. And they elect their own.
Big cities, Billings/Bozeman, Butte, and Great Falls have a ton of pull, but it's kinda balanced - Politically owned by Democrats, offset with business being largely Republican. That's why they tend to be purple over there, with a fair edge to the Democrats.
What often decides the game is the rural farmers, and they will always elect their own.
Without that, it's a tough row to oust Testercle.
Here's hoping... Though I think Rosendale has earned the seat if he wants it. Let Sheehy come up through the House.
