More broadly, support for Trump's deportation program has declined in recent months. Sunday's poll found that 51 percent of respondents disapprove of the program, while 49 percent approve. That marks a notable drop from a similar February poll, when 59 percent approved, and from 54 percent in a June poll.

The latest poll also shows 58% disapprove of Trump’s handling of immigration. That’s up 10 points from early March, when 48% disapproved, according to CNN’s figures. Nearly six in 10 oppose Trump’s efforts to arrest and deport people here illegally who don’t have a criminal conviction.

By tapping into other grievances, President Trump managed to turn one of the most fractious moments for his base into a unifying one.

President Donald Trump is threatening to hold up a stadium deal for Washington's football team if it doesn't restore its old name.
