Exclusive poll: Immigration concern spikes over separated families

Data: SurveyMonkey. Poll Methodology; Chart: Andrew Witherspoon/Axios

There's been a big jump over the last week in the percentage of Americans who say immigration is the most important issue facing the country, as they've been bombarded by the images and sounds of families being separated after trying to cross the border illegally, according to a new Axios/SurveyMonkey poll.

Why it matters: It's mostly Democrats who have shifted, and to a lesser extent independents — a sign that they're getting energized over the coverage. The survey was conducted before President Trump signed his executive order yesterday that's intended to stop the separations by detaining families together.
