If you receive fundraising e-mails from the Democratic Senatorial Campaign Committee, you’ve probably noticed this lately:

Click here to make a contribution of $50, $75 or more to the DSCC to help Democrats win a filibuster-proof Democratic majority on November 4.  Give by midnight August 31 and a group of Democratic senators will match every single dollar you give, effectively doubling your contribution.

Anyone know which senators are in this group or whether Tom Harkin is participating?

After Labor Day we should be ready to get another Use It Or Lose It campaign going.

Sven from My Silver State did a lot of research for this diary on how much each Democratic senator has given to the DSCC so far this cycle.
