Sen. Elizabeth Dole (N.C.), former chairwoman of the National Republican Senatorial Committee, brought in $1.7 million during the first three months of 2007, according to her campaign.

Dole’s re-election committee closed out the quarter with more than $1.5 million in cash. She raised more than $1 million in March alone.

Dole had about $250,000 on hand at the end of the 2006 election cycle, according to CQ PoliticalMoneyLine.

A recent survey by Senate Democrats, which claims that only one-third of Tar Heel State voters plan on picking Dole in 2008, suggests that Dole is vulnerable going in to her first re-election bid.
