Southlake Mayor Shawn McCaskill is among several northeast Tarrant mayors who donated to Tarrant County Judge Tim O'Hare's reelection campaign this summer.

McCaskill gave $250, according to campaign finance reports published Monday, Oct. 5, first reported by the Fort Worth Report. North Richland Hills Mayor Jack McCarty contributed $5,000, Keller Mayor Ross McMullin gave $500, and Fort Worth Mayor Mattie Parker and her husband David Parker gave $1,000. Mansfield Mayor Michael Evans was the lone mayor to back O'Hare's Democratic challenger, Alisa Simmons, contributing $1,000.

The gap is wide.

O'Hare, seeking a second term, reported more than $836,000 in available campaign cash as of Sept. 24. Simmons, a Precinct 2 county commissioner running for the countywide judge seat, had about $247,000.

The filings cover fundraising and spending from July 1 through Sept. 24. O'Hare raised about $415,000 over that stretch and spent about $290,000, mostly on consulting and canvassing. Simmons raised about $286,000 and spent nearly $75,000, largely on consulting, phone-banking and signage.

O'Hare's largest single donation was $100,000 from Texans United for a Conservative Majority, a political action committee led by West Texas oil billionaires Tim Dunn and Farris Wilks. The National Cutting Horse Association's Texas Events PAC gave $10,000. Republican attorney general nominee Mayes Middleton gave more than $5,000.

Simmons drew her biggest support from real estate developer Walter Horton, who gave roughly $98,000 across three installments. David Gunn of GM Financial gave $10,000, and U.S. Senate Democratic nominee James Talarico's campaign contributed $5,000. The majority of Simmons' donors gave $100 or less, according to the filings.

The fundraising gap grew over 2026. O'Hare raised about $314,000 in the first six months of the year. Simmons raised about $111,000 over that same period.

Republican incumbents outraised and outspent Democratic challengers in most Tarrant County races, according to the filings. Democrats outraised Republicans only in the district clerk and county clerk contests.

At a Sept. 15 True Texas Project meeting in Euless, O'Hare urged conservatives to rally for November. "If we all work, we will win. If we don't, we're probably going to lose," he said at the time.

Early voting for the Tuesday, Nov. 3 general election begins Oct. 19.
