Not American but it seems like a good decision from a strategic point of view. It gains her some potential right wing votes but doesn't actually require her to enact it in the same way republicans would, no wall or calling for people to be shot on sight.
There are no undecided voters in this election. No one who wants to vote for the Toupee is going to be won over by anything the Democratic party says. All they're doing with this is turning away voters on the left, who want an option beyond two conservative candidates.
For almost two weeks there it seemed like the Dems might have learned a lesson, but they're back to shooting themselves in both feet.
