Republicans can really only go up from here - this would probably be a horse-race in a head-to-head due to Republican dissatisfaction. As it stands, if Roberts isn't losing now, he's not going to lose in November.
I disagree. If Orman can get the Republicans that vote for Paul Davis in the Governor's race and Taylor consolidates a little more the Democratic vote, then I could see him slipping by with a plurality. I don't think we can say that the Republicans can only go up from here when Robert's opponents haven't defined themselves yet. Three-way races are volatile and I wouldn't draw any far reaching conclusions just yet.
