The political group associated with President Donald Trump is spending $10 million on television and digital advertisements in the Texas Senate race, according to a Saturday filing with the Federal Election Commission.

This is the first significant spending in a premier general election contest by MAGA, Inc., and reflects how a once-safe Republican seat in Texas may be viable for Democrats with the candidacy of James Talarico, a 37-year-old state representative.

Texas Attorney General Ken Paxton is the Republican nominee in the race. Trump’s endorsement helped Paxton to defeat the incumbent, Sen. John Cornyn, in a May primary runoff election.

Public disapproval of Trump over the economy and the Iran war has been a headwind for many Republican candidates. Voters generally go against the party in control of the White House in midterm elections and Democrats are hoping to gain control of the House and Senate — with Texas being a symbolically powerful indication of how the political map might be expanding this year.

The ads seek to highlight taxes as a dominant issue at a time when many voters have expressed concerns about continued inflation. Talarico has favored higher taxes on wealthier households and the two ads seek to portray him as seeking tax hikes more broadly while claiming that Paxton would give tax breaks to first-time homebuyers and families with children.
