WASHINGTON — Republican Texas Sen. Ted Cruz will report raising more than $4 million in the last three months, according to a Washington Examiner report on Tuesday.

Cruz’s Democratic challenger, El Paso Rep. Beto O’Rourke, has not yet announced his fundraising for last quarter. Quarterly reports are due on Sunday and aren’t available yet for either candidate.

In the first quarter of 2018, Cruz posted $3.2 million in donations, far less than O’Rourke’s $6.7 million haul — the most raised in a single quarter by any Texans running for the U.S. Senate in at least three decades.

O’Rourke has outraised Cruz in three out of the four quarters since he announced that he would challenge the Republican senator.

Cruz had $8.1 million in cash on hand compared to O'Rourke's $8 million after the first quarter, according to federal filings. The Examiner report says Cruz will have $10 million after a solid second quarter.

The latest poll by the University of Texas and the Texas Tribune from June 25 put Cruz 5 percentage points ahead of O'Rourke, with 17 percent of those responding with no opinion.

The nonpartisan Cook Political Report rates the race as competitive, but with a “likely Republican” outcome.

The Federal Election Commission has sent Cruz notices three times this election cycle noting that he had accepted individual campaign contributions above allowed limits. The excesses could stem from the structure of contribution forms on his website, which require donors to opt out of giving recurring monthly contributions, with no automatic cutoff once they’ve hit the limit.

O'Rourke has sworn off money from political action committees. According to the Center for Responsive Politics, a campaign finance watchdog group, some of his top donors are employees of universities and California-based tech companies such as Google's parent company, Alphabet, and Facebook. O'Rourke held a fundraiser in Los Angeles on Monday.

Texas donors accounted for 70 percent of O’Rourke’s funds in the first three months of 2018, according to his campaign.
