Tally: Outside GOP groups outspending Dems 7-1

A Democratic operative active in Senate races sends over this summary, from public sources, of outside television and radio spending on the races from August through last night:

Republican Third Party Groups — $43,664,661

Democratic Third Party Groups — $6,658,236 Colorado — Dems: $1.1 million / GOP: $7.6 million

Washington — Dems: $1.5 million / GOP: $4.2 million

Missouri — Dems: $794k / GOP: $7.2 million

Kentucky — Dems: $47k / GOP: $1.7 million

That's a more than seven-to-one advantage, if you're keeping score.

More on this from Jonathan Martin and CPI.

UPDATE: Some of the state numbers may not be current quite to last night.
