The script has most definitely been flipped on Senate battlegrounds in 2016.

This cycle, Republicans take nine of the 10 spots on Roll Call’s list of the most vulnerable senators. That’s a marked turn from 2014, when there were nine Democrats and one Republican.

The list features just the incumbents, so the ultra-competitive open-seat races in Nevada and Florida are not included. And it should also be noted that senators in spots six through 10 are not nearly as vulnerable as those at the top of the list.

We’ll update this list six months from Election Day, and again in the weeks leading up to Nov. 8, 2016.
