Republican House and Senate candidates are adopting one of President Donald Trump’s key issues – and his style - to get themselves elected in November.

Immigration has long been red meat to Trump’s base. At Nashville, Tennessee’s Municipal Auditorium last Tuesday, 5,500 supporters eagerly chanted “build the wall” and Trump’s use of a controversial term to describe MS-13 gang members — “animals!”

Will Immigration Get Trump Voters to Midterm Polls?

Will Immigration Get Trump Voters to Midterm Polls?

So far this election season, House GOP candidates nationwide have mentioned immigration in 34.3% of TV spots, ranking a close second to Pro-Trump ads (35.5%), according to of political .

“There’s been a lot of debate about whether these same [pro-Trump] voters will turn out to support other Republican candidates, and I think that’s why you’ve seen so many Republican candidates sort of trying to emulate Trump’s tone and approach on some of these issues,” said Dan Cox, Director of Research for the Public Religion Research Institute (PRRI), a nonprofit, nonpartisan research organization.

“Midterm elections typically are about the base, and this issue really animates the Republican base,” Cox said.

A recalls the history of Luis Bracamontes, an undocumented immigrant convicted of killing two California deputies, before a narrator issues a dire warning: “Democrats who stand in our way, will be complicit in every murder committed by illegal immigrants.”

The message falls in line with much of Trump’s recent rhetoric that Cox characterizes as “personal safety”-themed — one that garners a nationwide audience among his base of white working-class Americans.

According to a conducted by PRRI and , 62% among that demographic believe the growing number of immigrants threatens American culture. Among the same group, voters who favored deporting immigrants living in the U.S. illegally were 3.3 times more likely to support Trump than those who did not.

Historically, in midterm elections as compared to presidential election years. As a result, it is normal for candidates of either party to focus on their base of reliable, energized voters during those years.

But choosing to focus much of their attention on Trump’s hardline immigration policies this year comes with risks, explains Diana Mutz, a professor of political science and communication at the University of Pennsylvania, whose research in 2016.

“[Trump] is operating on the premise that being extremely anti-immigration actually won him votes. Our analyses actually suggest just the opposite — that yes, things like trade did win him votes but things like immigration actually did not,” Mutz told VOA. “They lost him votes because he was far too extreme.”

According to 65 percent of Americans say immigrants strengthen the United States “because of their hard work and talents,” while 26 percent consider them a burden “because they take jobs, housing, and health care.” Among Republicans, views are more evenly split — 42 percent hold favorable views, 44 percent unfavorable.

Trump’s message on immigration may be problematic in districts with large college-educated populations, says Cox. That includes those who may have initially supported Trump with reservations and are critical of his more controversial policies, such as or repealing Deferred Action for Childhood Arrivals (DACA) — a program that allows some 700,000 undocumented immigrants brought to the United States as children to live and work without fear of deportation.

But in addition to mobilizing moderate and Independent voters, a strong turnout among Hispanics could be another important factor, given among the bloc.

“Usually in midterms, people do play to the base because those are the only people who bother turning out … this year may be different,” Mutz said. “Everything I’ve seen suggests that people may come out in far greater numbers than they usually do.”

The prevalence of a national immigration debate among Republican candidates hasn’t had the same broad appeal across the aisle, as of House Democratic candidate ads, which place health care, anti-Trump, and social issues as the respective top three topics.
