If you're wondering why the DSCC and Harry Reid are leaning on Kerry and Bayh in particular, this may be the answer.

So far Kerry has given the senate election committee $15,000 and Bayh $30,000.

Just for some random points of comparison Biden ($230,000), Feinstein ($1,106,800), Rockefeller ($325,000), Salazar ($116,000).

I know Kerry's done a ton of campaigning for candidates around the country. I think he's a great Democrat. But he's sitting on a lot of money. And the DSCC could do a lot right now with money from these two.
