Roland Gutierrez, a Democratic state senator who has been an outspoken gun-control proponent since final 12 months’s bloodbath in Uvalde, Texas, introduced on Monday that he would search Senator Ted Cruz’s seat subsequent 12 months.

Mr. Gutierrez, whose district stretches from San Antonio to the Rio Grande and contains Uvalde, is the second main Democratic politician to enter the race, more than likely guaranteeing a high-profile main contest amongst Texas Democrats. Representative Colin Allred, a second-term congressman from the Dallas space, declared his candidacy in May.

Both candidates have entered the race vowing to focus their assaults on Mr. Cruz reasonably than on any Democratic rivals.

Mr. Gutierrez gained a measure of nationwide prominence as probably the most strident and uncompromising voices within the Texas Capitol pressing for gun control after the bloodbath that killed 19 youngsters and two lecturers at Robb Elementary in Uvalde final May. He is a well-recognized face on cable news, commenting not solely on the killings in Uvalde and the delayed police response but additionally on different mass shootings.

“I’m a proud gun owner and believer in the Second Amendment, but after 19 children and two teachers died, the Republicans wouldn’t even allow us an opportunity to talk about ways to protect our kids,” Mr. Gutierrez says in a video published on Monday to announce his candidacy. “It’s why we have to do something now.”

The challenge of gun violence, and the unwillingness of Texas Republicans within the state and on the federal stage to control weapons, is predicted to be a centerpiece of Mr. Gutierrez’s marketing campaign. Aides mentioned that Mr. Gutierrez wouldn’t be afraid to indicate his ardour on the difficulty, as he has finished throughout news conferences and on tv.

“There is a special place in hell for people who have this kind of problem staring them square in the face and have done nothing about it,” Mr. Gutierrez said in May, after a gunman killed eight individuals and wounded seven others at a mall north of Dallas.

Unlike Mr. Allred, who started his marketing campaign partly by presenting himself as a bipartisan politician, Mr. Gutierrez is playing that a way more combative and doubtlessly polarizing strategy will present a path to unseating Mr. Cruz and successful statewide workplace in Texas. Democrats haven’t finished so in a long time.

As a state senator, Mr. Gutierrez pressed for a variety of measures so as to add restrictions to gun purchases, together with elevating the age to purchase AR-15-style rifles and increasing background checks, which polls have proven are broadly standard in Texas. None of the payments handed the Republican-dominated Legislature.

Beto O’Rourke, the previous El Paso congressman, supported the identical set of gun management insurance policies throughout his unsuccessful marketing campaign for governor final 12 months. Mr. Gutierrez is betting that the message would resonate otherwise coming from somebody together with his private biography, a gun-owning Hispanic consultant from a largely rural district of South Texas. Mr. O’Rourke additionally challenged Mr. Cruz, in 2018, and narrowly misplaced.

Mr. Gutierrez’s aides mentioned that the bloodbath in Uvalde would function the prime instance of how low-income and dealing Texans have been being mistreated by these in energy like Mr. Cruz.

Mr. Gutierrez begins with a fund-raising drawback. Mr. Allred’s marketing campaign mentioned that it had raised $6.2 million within the two months since asserting his marketing campaign. Mr. Gutierrez, against this, was prevented by Texas regulation from elevating cash till mid-June, after the tip of the state’s legislative session.

But aides to Mr. Gutierrez mentioned that they didn’t anticipate that fund-raising can be an issue, particularly in a basic election, as a result of Democrats have historically been prepared and wanting to spend cash to attempt to defeat Mr. Cruz.
