Economy and jobs

Tester was one of two Democratic senators to filibuster the
American Jobs Act in 2011. It was reported that he was not concerned about the surtax on some families to pay for the plan, but was unsure that the new spending would actually create jobs. "I've got more of a concern about a state aid package ... and how the money is going to be spent and whether it's really going to create jobs," he explained.
Tester was the only Democratic senator from a Republican-leaning state to oppose a stopgap funding measure to end a
three-day government shutdown in 2018 and reopen the federal government.
Tester became one of the Democrats in the Senate to support the
2018 Economic Growth, Regulatory Relief and Consumer Protection Act, a bill that partially repealed
Dodd-Frank and relaxed key banking regulations. As one of at least 11 other Democrats, he argued that the bill would "right-size post-crisis rules imposed on small and regional lenders and help make it easier for them to provide credit".

Miles City. 'I think we should start hunting them again!' Tester said. The kids let out their loudest cheer of the afternoon."
Tester tried to revive a bill that was meant to be a compromise between the conservationists and the timber industry. The bill would put 700,000 acres of wilderness aside for "light-on-the-land logging projects" with the intention of creating jobs in the flagging industry. It was noted that Tester was not "winning admirers on his side", with some liberal environmentalists saying that would give lumber mills control of the national forests.
Guns
Tester is a gun owner.
On
gun rights, the
NRA Political Victory Fund gave him an A- rating in 2012. This was downgraded to a D in 2018 after he voted against confirming
Brett Kavanaugh to the U.S. Supreme Court. Tester supports efforts to loosen restrictions on gun exports, saying it would help U.S. gun manufacturers expand their business and create more jobs.

Tester said in 2017 that Democrats should consider a
single-payer health care system.
In the summer of that year, he said that health care needed reform but that the latest GOP attempt at reform was a "train wreck" that would "strip health care away from millions of Americans". He said that Democrats should "work to fix what's wrong with the current healthcare system in a bipartisan way. And that means going through committee process, not doing it in a dark room with a select few, but going through the committee process and getting good ideas from everybody". Reminded that some Democrats "believe that compromise on this issue is not only unprincipled but unnecessary", Tester said the issue was "too important... not to try to help remedy the problems".
Immigration

In 2010, Tester voted against the
DREAM Act, which would have created a pathway to citizenship for the foreign-born children of illegal immigrants. He has said, "Illegal immigration is a critical problem facing our country, but amnesty is not the solution. I do not support legislation that provides a path for citizenship for anyone in this country illegally."
In 2017, Tester criticized Trump for saying that he would cancel
DACA in six months. "I don't support what the president did", Tester said. "I think it's ill-informed, I think it rips families apart, and it's not what this country stands for." Asked if he would now commit to voting for the DREAM Act, he said, "I support comprehensive immigration reform."
