Nerd hero Nate Silver tries to make some sense out of all the contradictory Murray vs. Rossi polling and, after the late addition of today's Elway Poll to his pile, throws up his hands:

Not even going to try to unpack this one—this has been a weird year for polling and it's just hard to know who you can trust; hopefully things will converge some before we get to the stretch run in August/September.

Yikes. But one thing we will know long before August/September—and, in fact, have to know by the June 11 filing deadline—is whether Rossi, still playing coy, is officially in or out.
