According to The Green Papers, now that Taylor's out,
there still are other candidates in this race besides Orman and Roberts; 3 to be exact including the Libertarian candidate. Milton Wolf lost to Roberts partially because of that vote split between the anti-Roberts people, so I would really hope Batson (L) and the others do the right thing as well and drop out. It would not only help the Dems in the long run for majority purposes, but take out one of the most partisan gridlocked Senators and end the near century GOP trend on this one specific Senate seat.
There might be a large number of drop-offs now among Taylor supporters/Democrats, but even though this is Kansas, it might actually help him in the long run if he agrees to caucus with the Democrats. If you take the last PPP and SurveyUSA polls and add the Taylor + Orman vote, Roberts loses by double digits, so a lot is at stake at who they vote for now.
