The standard pivot from primary to general election could make life hard for Republican candidates this summer, as the focus on immigration shows no signs of waning, and there appears to be a wide gulf between the general electorate and GOP voters.

A Quinnipiac poll of 905 voters conducted from June 14-17 found widespread opposition to the administration’s family separation policy among almost every cohort except Republicans. According to the survey, “voters oppose 66-27 percent the policy of separating children and parents when families illegally cross the border into America,” Quinnipiac reported on Monday. But Republican voters, the poll found, “support the separation policy 55-35 percent, the only listed party, gender, education, age or racial group to support it.”
