Johnson

See this about Senator Johnson, who seems to be remaining neutral about Lamont's win in the Connecticut primary:

But let's look at the Democratic Senators in our new category, which I'm calling "firm about not being firm" when it comes to the interesting situation in Connecticut.

Drey Samuelson, Chief of Staff for Senator Tim Johnson (D-SD), responded quickly and very nicely saying he would get in touch with the Senator and inquire. He then got back to me, saying "Tim sees no need to endorse either candidate—it's up to the voters of Connecticut to decide who represents them."
