AUSTIN (CBSDFW.COM/AP) — Sen. Ted Cruz says his Democratic opponent, U.S. Rep. Beto O’Rourke, more than doubled him in fundraising over the past three months — continuing a surprising donation losing streak and potentially tightening a November race that once looked like a slam-dunk.

O’Rourke says he raised more than $10.4 million over the past three months. He announced his latest fundraising numbers Wednesday night on Facebook Live.

O’Rourke said Wednesday that his donations through June 30 came from nearly 216,000 contributors. He has more than $14 million in campaign cash on hand.

O’Rourke’s campaign has shunned donations from outside groups but still racked up impressive fundraising totals, repeatedly outraising Cruz.

A onetime punk rocker, O’Rourke has repeatedly outraised Cruz since announcing his Senate bid in March 2017. His high-energy campaign has attracted national attention.

A Democrat hasn’t won any Texas statewide office since 1994. It’s the longest losing streak in the country.
