Whe you're up you're up, when you're down you're down

And when you are a poll, your just quantum.

L.A. Times/Bloomberg Poll: McCaskill 45% Talent 48%
Mason-Dixon/McClatchy Poll: McCaskill 46% Talent 43%
SurveyUSA Poll: McCaskill 45% Talent 48%

The L.A. Times notes that rural voters will likely decide whether Democrats take the Senate this fall.

The Mason-Dixon poll finds that the two candidates' favorable/unfavorable are within a point of each other. It also notes that 81% are voting for a candidate despite a 37%/57% right track/wrong track result.

SurveyUSA found decreasing support for the stem cell initiative. What was a 30-point "certain yes" margin on October 12 has become a 9-point margin. There are likely some observers who are collecting on bets right about now.

The senate numbers are all within the margin of error (+/- 5 for LAT, +/-4 for M-D and +/- 4 for SUSA).
