A bit of free advice to political consultants, commentators, and politicians: Do not mock voters for having concerns about policy issues, as the talking head squadron at MSNBC did on Tuesday night.

During election night coverage of the Super Tuesday primary results, MSNBC hosts and Democratic Party activists Rachel Maddow, Joy Reid, and Jen Psaki had some rather contemptuous remarks to make about an exit poll from Virginia that showed immigration was a top concern to primary voters.
