lmao, is McCaskill entrenched?
Lol, McCaskill will never be entrenched. As long as she is the Democratic incumbent, this seat will always be the most likely "red" state to flip.
Also, I'm not sure it's the Republicans who are "overconfident" about this race, considering that some people here are equating Hawley with Akin and believe McCaskill is favored to win reelection.
Another Democrat fell 3 points short of knocking out an incumbent republican while trump won Missouri by almost 20. McCaskill beat Akin by 15 in 2012 while Donnelly put away a similar opponent by only 5. And this was a year that was not as good for democrats as 2018 almost certainly will be. Donnelly is the only democrat that is in serious trouble right now in a trump midterm.
