Final thoughts on Indiana – Richard Mourdock defeating a sitting incumbent Senator is a huge deal. Senators very rarely lose their party’s nomination. This should send shockwaves through the GOP. Lugar was, after all, one of the only six real Republican incumbents running this cycle and Orrin Hatch, another Republican incumbent up this year, has spent months also trying to fend off his own primary challenge.
This will send the message to all sitting Republicans that incumbency does not equal safety. If you don’t stick to conservatives’ principles you can be challenged and defeated. I wouldn’t be surprised if elected Republicans were even more unified and conservative moving forward.
