Awesome. Susan Collins still underwater, what a joy. Best takeaway from this: Ernst is underwater as well, this might make Iowa competitive, as she's previously had very high approval ratings.
Also underwater: Tillis, Gardner, McConell. Not getting any hopes up for the last one though.
McSally just has net approval of 2%, very doable race.
Perdue (Georgia) might be a long shot at this point in time, sadly.
