Hotline On Call

The next fundraising report that senators up for reelection in 2014 file will be the year-end report, and we'll see in those numbers who's ramping up their fundraising as the new cycle kicks off. In the meantime, here's a look at where potential vulnerable senators were, money-wise, as of the third quarter report.

Some -- notably Senate Minority Leader Mitch McConnell -- are already fundraising at full tilt, while others, like Sen. Jeanne Shaheen, D-N.H., haven't been focused on fundraising yet.

Several candidates face the prospect of possible primary and general election challenges:

Senate Minority Leader Mitch McConnell, R-Ky.: $6,793,000.

Sen. Max Baucus, D-Mont.: $3,100,000

A number of Democrats face the prospect of tough re-election campaigns, and need to gear up early:

Sen. Kay Hagan, D-N.C.: $1,303,000.

Sen. Jeanne Shaheen, D-N.H.: $338,000.

Sen. Mark Begich, D-Alaska: $681,792.

Sen. Tim Johnson, D-S.D.: $1,222,0000.

Sen. Mark Pryor, D-Ark.: $1,791,000.

Sen. Mark Warner, D-Va.: $3,383,000.

Sen. Mary Landrieu, D-La.: $1,614,000.

Sen. Jay Rockefeller, D-W.V.: $704,000 (note: Rockefeller has put in money from his personal fortune in the past, and could do so again).

Sen. Al Franken, D-Minn.: $1,059,000.

Sen. Tom Harkin, D-Iowa: $2,745,000.

Sen. Mark Udall, D-Colo.: $1,110,000

And some GOP incumbents are running in red states but face potential primary threats:

Sen. Lindsey Graham, R-S.C.: $4,346,000.

Sen. Saxby Chambliss, R-Ga.: $1,399,000
