You're the polling king Tim. Here are some immigration polls.
73% of Republicans favor DACA recipients staying in the US. Even Trump favors them staying.
39% of Americans think the US/Mexico border issues is a crisis. 35% think it's a major problem. That's 74% of Americans, not Republicans, Americans.
62% of Americans think healthcare for illegal immigrants is a bad idea.
66% of Americans think decriminalizing illegal border crossings is a bad idea.
Not sure what you mean by pro-immigration, but a majority of Americans want stronger borders and don't want an increase in immigration into America or resources given to illegal immigrants.
