People leaving regions because of the results of one election is one of the major problems with Atlasia.
There's a permanent right-wing majority in the Mideast. That's not likely to change anytime soon.
Certainly not if left-wingers keep fleeing the region in protest.
It's not like it really matters that much. The latest PJ poll shows the Mideast would rather have JCL as the next Mideast Senator rather than Snowstalker which shows this region is doomed. Adam Griffin said it himself a few weeks ago that the Labor force that once existed in this part of Atlasia is no longer present.
The Feds have the IDS and the Mideast while Labor has the Midwest and Pacific, and it's going to be really hard for any of that to change. Simple as that.
Pacific is Progressive territory.
