Looking at Senate Primary Turnout so far..

[Roll Roons]

I think what you’re forgetting is that Kentucky had a hyper-competitive R race while D’s did not, so turnout was skewed. Rand Paul, being a low quality incumbent, induced huge turnout from the famous Elliot county trying to primary him

The only vaguely competitive federal primary in Kentucky was for the safely blue KY-03 (which ended up not being close at all).

A mixed bag tonight for both sides. Dems get easily their best performance so far, netting 78% of the turnout in Vermont. But the GOP gets 57% in Wisconsin, placing serious doubt on that being a pickup opportunity for Dems. Connecticut is a little weird, as a lack of contested primaries leads me to use the SOS race. But for what it's worth, D's got 55% there.

I still think Ron Johnson is a slight favorite, but tbf, Republicans had a very hotly contested gubernatorial primary in Wisconsin while Democrats really had nothing statewide.
