Former Hewlett-Packard CEO Carly Fiorina (R) and former Rep. Tom Campbell (R-Calif.) are locked in a tight race for the Republican Senate nomination in California. New fundraising numbers released by Fiorina’s campaign Tuesday also show the pair are in a close contest on the money front.

Fiorina nudged past Campbell in first-quarter fundraising, pulling in $1.7 million, the campaign announced. Campbell revealed last week that he raised $1.6 million in the quarter.

Fiorina has the advantage, however, of being capable of pouring significant personal resources into the race. She loaned her campaign $2.5 million last fall, which helped boost her cash-on-hand total. She ended March with $2.8 million in the bank. Campbell did not reveal how much cash he had in the bank as of March 31.

A third Republican, state Assemblyman Chuck DeVore, has not released his fundraising totals for the quarter.

In a statement announcing her latest financial totals, the Fiorina campaign highlighted the fact that she has now raised nearly $2.8 million for her campaign since the fall from 8,285 individuals.

The Republicans in the Senate race still have yet to demonstrate, however, that they are capable of matching Sen. Barbara Boxer’s (D) resources or donor support, a critical factor in the contest.

Boxer’s campaign announced Monday that she raised $2.4 million in the first quarter for a total of more than $13 million raised in the 2010 election cycle. The campaign now has $8.7 million in cash on hand.
