(1) Poll Position: Republican nominee Joe Miller has pulled back into the lead in the last two major polls -- ahead of both Democrat Scott McAdams and the incumbent write-in candidate.
(2) Party Alignment: The incumbent write-in candidate recently started dissembling about which party she might caucus with in the Senate, if re-elected. Now she's saying definitively that it would be the GOP.
(3) National Republican Support: Despite finger-pointing and implications that the NRSC was secretly backing the incumbent over Republican nominee Joe Miller, NRSC Chairman John Cornyn has again asserted the group's unwavering backing of Miller.
One near certainty: Now that we think we're finally a handle on it, this race is inevitably going to take another wild, unexpected turn. It's going to be a long, long night.
