Congress should seize this rare chance at comprehensive immigration reform

Greg Abbott isn’t someone most Chicagoans look upon with fondness.

And for good reason.

Leave aside the nasty politics for a moment, though, and in a key respect Abbott has done Chicago and the country a favor.

The Texas governor has sowed chaos in our local politics by dispatching multiple busloads of migrants to Chicago with little notice and absurdly minimal consultation with authorities here.

His motives are less than pure, that’s for sure.

But he has effectively called the bluff of local politicians on their repeated statements of welcome to migrants.
