(CNN) Sen. Michael Bennet raised $2.1 million in the third quarter of 2019, his campaign tells CNN, a sum that will likely make him one of the lowest-fundraising Democrats in the 2020 presidential field.

The number is down slightly from the $2.8 million Bennet had raised in the second quarter.

But he and his advisers, fueled by the feeling that they can run an inexpensive and focused campaign without the kind of money other candidates have in the bank, tell CNN that the Colorado Democrat plans to stay in the race until at least the New Hampshire primary on February 11 and to run a race focused on pushing policy differences with the party's left flank.

"I'm in this race to win the nomination and defeat Trump," Bennet told CNN, "so there's no doubt I'll be at the Iowa caucus and New Hampshire primary."

Shannon Beckham, Bennet's spokeswoman, said the campaign will be in the race until New Hampshire because they are running a "lean, strong campaign" that has the "resources to compete and win."
