Former state Sen. Cal Cunningham, who is running in the Democratic primary for Senate, burned through $198,000 during the first two weeks of April.

Cunningham launched his first ad of the primary during that time. That left him with $346,000 in the bank for the final sprint to the May 4 primary.

Cunningham’s top primary opponent, Secretary of State Elaine Marshall, reported spending just $57,000 from April 1 to 14, leaving her campaign with $171,000 as of April 14. Her campaign’s first ad is running this week.

The Democratic candidates aren’t expected to leave anything in the bank, so the eventual nominee will have a lot of catching up to do to be able to be competitive with Sen. Richard Burr (R) this fall.

At the end of March, Burr reported $5.3 million in the bank after raising nearly $1.6 million in the first quarter. Burr, who also dropped his first television ads in the first two weeks of the month, spent about $537,000 from April 1 to 14.
