Warren, a star among the party’s liberal base, called on supporters to give money to Kentucky Secretary of State Alison Lundergan Grimes in an e-mail shared among potential supporters Saturday. The e-mail was also circulated earlier in the week.

“Right now, the polls in Kentucky are tied — and you can bet that Mitch McConnell and his powerful friends will spend whatever it takes to beat Alison and win control of the Senate,” Warren wrote.

Warren’s assistance in Kentucky helps make up for the absence of Senate Majority Leader Harry Reid (D-Nev.), who signaled Friday who would not raise money for McConnell’s opponent.

"I don't think she needs much of my help. She seems to be doing pretty well,” he told Bloomberg Television.

Relations between Reid and McConnell have been at a low point since November when the Democratic leader used a controversial tactic known as the nuclear option to strip Republicans of the power to filibuster nominees.

The left-leaning website Daily Kos reported on Warren’s fundraising e-mail earlier in the week.

Warren is also raising funds for Michelle Nunn, the daughter of former Sen. Sam Nunn (D-Ga.), who is running for Senate in Georgia, and West Virginia Secretary of State Natalie Tennant, a Senate candidate in that state.

“The Republicans running against Michelle are all fighting with one another to decide which will be the most ultra-right wing extremist in the Senate,” Warren wrote. “We already have plenty of Senators carrying the flag for the Tea Party, we don't need another one.”

Hopes of winning at least one of the two Republican-held seats in Kentucky and Georgia figure significantly in the Democratic Senatorial Campaign Committee’s strategy for keeping control of the upper chamber.

Warren’s fundraising team helped Lundergan Grimes outraise McConnell between July and September, an impressive feat Republicans attributed to Warren’s fundraising team.
