On September 12, 2019, Beto O'Rourke said "Hell yes we're going to take your AR-15, your AK-47" during a Democratic presidential primary debate. In response, Cain tweeted "My AR is ready for you Robert Francis [O'Rourke's first and middle name]." Replying to Cain’s comment, O’Rourke called the tweet a "death threat." "Clearly, you shouldn’t own an AR-15 — and neither should anyone else," O’Rourke tweeted. Cain responded with a tweet, "You’re a child Robert Francis." Twitter gave Cain 12 hours to remove the post. After did not, the company removed Cain's "My AR is ready for you" tweet, saying it was against the site's policy against violent threats. Cain was suspended from Twitter for 141 days. On January 31, 2020, the day the social media company lifted its suspension of Cain's Twitter account, Cain tweeted a screenshot of the interaction between him and O'Rourke writing, "But seriously @twitter, y’all banned me for this."

Cain ran unopposed in the Republican primary election held on March 6, 2018. On July 5, 2017, Terry Sain of Baytown, Texas announced that he would be running against Cain in the 2018 Republican primary. However, just before the December 11, 2017, deadline to file for a place on the primary ballot, Sain announced that he was no longer going to challenge Cain. Citing the difficulties of running a campaign as a reason he dropped out of the race, Sain told The Baytown Sun that running in the campaign "wasn't quite as easy of a road as I thought it was going to be." In the November 6, 2018, general election Cain ran unopposed. On November 18, 2019, Robert Hoskins of Baytown, Texas announced he would be running against Cain in the 2020 Republican Primary.

On June 22, 2018, Cain and three other men snuck into the Texas Democratic Party's state convention being held at the Fort Worth Convention Center in Forth Worth, Texas where Cain and three other men handed out 100 yard signs which read, "This home is a gun-free safe space" to convention attendees. Eventually, convention goers recognized who Cain was, and he and the other pranksters were forced to leave. When asked about the stunt, Cain said he distributed the signs as "irony" and stated, "It's amazing how many people took one and thanked us. They said they would put it in front of their house. I think it's funny. Nobody should put this in front of their house."

In 2017, Mark Jones from Rice University in Houston released a study of votes in the 85th Texas legislature that indicated Cain was considered the "most conservative" legislator in the Texas House. The interest group, Texans for Fiscal Responsibility, founded by Michael Quinn Sullivan, scored him 100 percent and rated him as one of the top 10 "Best Legislators of 2017". Texas Values, a Texas-based organization that advocates for "traditional family values," scored him 100 percent and named Cain a "Faith & Family Champion". Young Conservatives of Texas rated him 100 percent. The Texas division of the National Federation of Independent Business, an organization that lobbies for small businesses, gave him a 100 percent rating. The Texas chapter of Eagle Forum scored him a 93 percent (the second highest score awarded). Texas Right to Life scored him 100 percent.

Cain was named one of "The Worst Legislators of 2017" by Texas Monthly, which wrote "We tried really hard to give Briscoe Cain a pass. But he left us little choice. When we asked Capitol insiders for Worst list suggestions, his name, almost universally, was the first one mentioned."

On October 10, 2017, protesters at Texas Southern University (TSU) prevented Cain from speaking at a Federalist Society event on campus. Cain was invited by the president of TSU's Federalist Society student chapter to speak to students at the traditionally black university. He planned to talk about the Texas Legislature's most recent special session. During that session Cain proposed an amendment to a budget bill which would prevent the state of Texas from paying for sex reassignment surgery and hormone therapy for inmates in prison, and he voted in favor of a proposed "bathroom bill". Protesters claimed that Cain "has ties to the Alt-Right and is anti-LGBT" and drowned out Cain's attempts to speak. They were removed; as Cain began to speak again the school's president ordered the protesters be brought back in and canceled the event, saying the Federalist Society chapter was an unregistered student group and the event was "unapproved". Cain said in a statement that the talk had been scheduled for months, and that he was "brought into a room in which the administration had specifically requested the talk occur. Then Black Lives Matter came in and bullied the administration into ending the event." James Douglas, the interim dean of TSU's Thurgood Marshall School of Law, said the event had been cleared with him and that he was investigating the incident. He said, "We have a process here in the law school, and they went through our process. The speaker had a First Amendment right to be heard by the students that invited him." A student who had helped organize the protest said that "[w]ith his First Amendment right to espouse hate comes our First Amendment right" to protest. Cain, a partner at a law firm where he practices First Amendment law, said he intended to sue the school and its president for infringing upon his First Amendment rights.

Since being elected in 2016, Cain has consistently ranked as the most conservative member of the Texas House.

In December 2015, Cain successfully defended the religious rights of Beaumont police officers when the city banned them from having Bible study during lunch breaks.

From these invoices he claimed the Texas schools were using tax dollars to purchase aborted fetal tissue, since Planned Parenthood was known to give fetuses to the California company. In a statement, Texas Tech University Health Sciences Center El Paso said that it strictly followed federal and state guidelines. Cain is the Texas legal counsel to Operation Rescue.
