Cruz’s campaign raised $12.2 million last quarter, giving him a total of $26.5 million raised during the campaign so far. He will report $13.5 million in cash on hand, campaign officials told The Post, meaning he spent about 51 percent of what came in.

The total raised by Cruz falls short of the $20.2 million reported by retired neurosurgeon Ben Carson. But the burn rate — the rate at which Cruz is spending money — is low compared to many of his competitors who have released results for the most recent reporting window: Florida Sen. Marco Rubio tore through 81 percent of the money he pulled in, Ben Carson spent 64 percent of his cash and Sen. Rand Paul (Ky.) spent $2 for every $1 donated, all according to Washington Post calculations. Former Florida governor Jeb Bush has not yet released his fundraising totals for the last quarter.

Cruz’s campaign said it has so far spent $3.7 million to run the non-fundraising portion of its campaign operations, just 14 percent of the total.  The campaign meantime invested much of its resources back into high-tech fundraising efforts that used data analytics and a technique called “donor modeling.”
