so the Dems expect them to vote Dem next month ?
They're delusional if the do.
Just the logistics of getting them fake IDs, addresses, voter registrations, and taking them to the polling stations should be deterrent enough, but they (the Dems) would have to instruct them (in Spanish) on how to tick the right boxes, or use the voting machines correctly, all the while pretending that they belong there and know what they are doing.
They would also have spread them around to various polling stations (to avoid suspicion) and have them vote mainly in those "battleground" districts where a few hundred illegal ballots could make a difference, all the time avoiding someone recognizing them and saying "You look familiar--Aren't you one of those 'caravan' immigrants I saw on Youtube?"
This tactic does not bode well for the Dems--at least not for the 2018 elections.
As an "issue," I don't think the caravan of illegals will drum up the kind of sympathy the Dems might be hoping for.
U.S. citizens are getting tired of being "shamed" into accepting lawbreakers into the country by crazy liberals shouting "you meanie, racist, family breaker-upper, etc."
No, they expect several photo ops and videos of mean right wingers ripping kids away from moms -— just in time for the mid-terms.
