This is just one state, and it has experienced a migrant surge unlike virtually any other state not on the southern border.

But it’s hardly the only evidence that the Democratic base and the country are shifting in a more concerned and immigration-skeptical direction — and in a particularly troublesome way for President Biden and his party.

A Fox News poll this month showed that a majority of Democrats were at least “very” concerned about border security. And last month, the same pollster showed three-quarters of Democrats describing the situation at the southern border as either an “emergency” or a “major problem.” That’s double the 37 percent saying the same in early 2019.
