How about we just say Iowa is too close to call?

It seems like daily a new poll comes out that places one of the three top democrats in the lead, so I suggest that we just say, "It's going to be close". Today, John Edwards is close in one poll:

The survey, which was completed by Edwards pollster Harrison Hickman on Wednesday night, shows Sen. Hillary Rodham Clinton (D-N.Y.) leading among likely caucus participants with 27 percent, followed by Edwards at 24 percent and Sen. Barack Obama with 22 percent. The race is even tighter when only definite caucus participants are included -- with Clinton at 26 percent, Edwards at 25 percent and Obama at 23 percent.
