Trump’s harsh immigration tactics are taking a political hit as new polls show a majority of Americans feel federal agents have “gone too far” in enforcing immigration laws.

It’s not just Democrats who are concerned, but also independent voters who are expected to play a major role in the upcoming midterm elections.

“The base loves it, but it’s an issue for the independent voters who decide elections in this country,” said Alex Conant, a veteran Republican strategist. “Independents want a strong border and they want to deport criminals, but they’re really uneasy with having masked federal agents going around in neighborhoods, deporting anyone that they see — as the Democrats are portraying it.”

After months of aggressive enforcement, Trump’s signature issue that twice got him elected is now turning into a liability ahead of this year’s midterm elections.
