PORTSMOUTH, N.H. — Sen. Ted Cruz has raised $3 million since winning the Iowa caucuses Feb. 1, his campaign said Thursday.

Cruz's campaign raised more than $19 million in the last quarter and ended the year with about that much in the bank, the campaign has said. Cruz (R-Tex.) touts his fundraising success on the campaign trail, telling audiences that he has more money in the bank than many of the candidates combined. He also uses the money to bolster his argument that a conservative candidate coming out of Iowa can win the presidential nomination.

“The conservative is supposed to be broke, and instead we’ve got the resources to compete nationally, combined with a grassroots army from the ground," Cruz told reporters on his plane earlier this week.
