O’Rourke has also proven to be a very adept fundraiser. As of June 30, he had $23.8 million receipts for cycle, including $10.4 million in the 2nd quarter; 41 percent of the 2nd quarter receipts were in contributions of less than $200. After spending almost $4.5 million last quarter, he finished with $13,961,359 in the bank. O’Rourke doesn’t accept contributions from PACs and has asked super PACs to stay out of the race. By contrast, Cruz had $23.7 million in receipts for the cycle, including almost $4.1 million in the second quarter. The campaign spent $2 million in the second, posting a cash-on-hand total of $9,299,366 as of June 30.

Both campaigns are going to need every dime they raise in a state that is as expensive as Texas. Neither candidate is on the air, but it will be interesting to see if the O’Rourke campaign adopts a more conventional broadcast media strategy after Labor Day.

Recent polling has indicated that the race has closed.
