Stable share of U.S. Muslims identify with or lean RepublicanMany more U.S. Muslims identify with or lean toward the Democratic Party than the GOP (66% vs. 13%), but the share who are Republican has held steady over the last 10 years, including after the election of President Donald Trump, according to a new analysis of Pew Research Center survey data collected between 2007 and 2017.

In 2007, 11% of Muslims identified as Republican. The share changed very little in surveys conducted by the Center in 2011 (11%) and 2017 (13%).

Sizable shares of both Republican and Democratic Muslims are critical of the way both parties treat U.S. Muslims. Nearly six-in-ten Republicans (57%) and about half of Democrats (47%) say neither party is friendly toward Muslims in America.

This criticism may be one reason a relatively large share of Muslims neither identify with nor lean toward either party. Indeed, U.S. Muslims are twice as likely as the public overall to say they lean toward neither major political party (20% vs. 9%).

Muslim Republicans less supportive than Democrats of immigration, big governmentIn some ways, U.S. Muslims who identify as Republicans are demographically similar to Muslims who are Democrats. For instance, similar shares in both groups are under age 40 (58% vs. 60%) and are immigrants (52% vs. 57%).

There are some demographic differences, however. U.S.-born blacks make up a smaller share of Muslim Republicans than Democrats (6% vs. 15%). Republican Muslims are somewhat less likely than their Democratic counterparts to have graduated from college (22% vs. 36%).

There also are some differences in their views of important issues, including immigration. Muslim Republicans are much more likely than Muslim Democrats (45% vs. 11%) to say immigrants are a burden to society because they take jobs, housing and healthcare, according to a survey conducted by the Center between January and May 2017. There also is partisan divide on this issue among those in the public overall, according to a separate survey conducted in June and July 2017.

Half of Muslim Republicans say Trump is unfriendly toward Muslim AmericansRepublican Muslims in general are also more likely than Democrats (50% vs. 23%) to say they prefer a smaller government with fewer services. But the partisan divide on this issue among Muslims is narrower than it is among the overall public. On other questions, such as views of homosexuality, or on measures of household income and religious commitment, the Center did not have an adequate sample of Muslim Republicans to measure partisan differences.

As might be expected, Republican Muslims are less likely than Democrats to see the Republican Party generally, and President Trump specifically, as unfriendly toward Muslim Americans. Still, sizable shares see their own party – and Trump – as unfriendly. In the 2017 survey, around half of GOP Muslims (52%) said Trump is unfriendly toward U.S. Muslims and about a third (34%) said the same about the GOP in general.
