Former Vermont Gov. Howard Dean (D) will headline eight fundraisers for the Democratic House and Senate party committees before the November election in hopes of driving small-dollar contributions to the organizations to boost their chances this fall.

The fundraisers, which began Tuesday in Seattle and will end Oct. 4 in New York, are the latest effort by Dean to bolster the party’s downballot chances.

“In order to ensure that Democrats win back both houses of Congress again, we must encourage everyone to participate in electoral politics,” Dean said in a statement.

Four of the low-dollar events (ticket prices top out at $100) will benefit the Democratic Congressional Campaign Committee; the other four will raise funds for the Democratic Senatorial Campaign Committee.

“Howard Dean had demonstrated a tremendous amount of excitement within our party, and we couldn’t be more excited that he is aiding our efforts to take back the U.S. Senate,” said DSCC Communications Director Brad Woodhouse.

Dean has proved to be one of the most effective fundraisers in the party this election cycle. He raised more than $50 million for his unsuccessful presidential primary campaign earlier this year and has raised $1.2 million for his new political action committee, Democracy for America, in its first three months of existence.

He has also helped an array of House and Senate candidates raise money for their individual campaigns.
