Former Democratic state senator Wendy Davis will face Chip Roy, a freshman Republican from Hays County, in the 21st Congressional District, a race that is sure to draw national attention.

Davis easily won the Democratic nomination on Tuesday, beating Jennie Lou Leeder, a swim coach who chaired the Llano County Democratic party for a decade, by a margin of 86.2% to 13.8%.

The district, which stretches from Austin to San Antonio and encompasses six Hill Country counties, has long been in Republican hands.

But Roy squeaked by Democrat Joseph Kopser in 2018, putting the district on a target list for national Democrats.

Davis, who unsuccessfully ran for governor in 2018, is a prodigious fundraiser.

She outraised Roy by more than a 2-to-1 ratio in the fourth quarter last year.

But both Davis and Roy finished the year with roughly $1.2 million in the bank.

Davis raised just over $900,000 during the last three months of 2019. She has raised $1.8 million this election cycle.

Roy reported raising $376,000 during the period. He has raised $1.5 million this election cycle.

"To every voter who trusted me with your vote, to every volunteer who knocked on doors, to every Texan who donated anything they could — thank you," Davis said on Twitter on Tuesday.

Roy campaign spokesman Nathan McDaniel told the American-Statesman in January he was "not worried" about the fundraising gap.

"Wendy Davis continues to raise big money from far-left liberals who want nothing more than to give another rubber-stamp vote for Nancy Pelosi’s radical agenda," McDaniel said in a statement. "Wendy is very experienced raising and wasting millions of dollars on losing campaigns."

Davis raised more than $30 million in her 2014 bid for governor. Gov. Greg Abbott, running his first campaign for governor, however, raised more than she did, and Davis lost to Abbott by more than 20 points.
