-If elected, with whom would he caucus?
-There is only one head to head poll for this match-up: from PPP a couple weeks ago.
-Roberts is now more vulnerable. But, by how much?
What I have done is use the recent PPP and Survey USA/KSN-TV poll. From PPP I use the head to head of Roberts/Orman and Roberts/Taylor (a little more weight to the former rather than the latter). I then took the Survey USA/KSN-TV poll between the three candidates and used the margin between Taylor/Roberts. This way I was able to incorporate two polling firms. I was able to incorporate the only poll on this match-up, as well as account for a possible Roberts lead now that Taylor is officially out.
I have further, refrained from placing Orman with either party. I, therefore, am leaving him as an independent in my scoreboard tabulations. He will, however, serve as the de-facto DEM for my "momentum" tracker. I am giving Orman a SLIGHT, MoE edge right now over incumbent Senator Roberts.
