The Guardian (a left-of-centre British newspaper) did something similar in 2004, getting volunteers to phone voters in battleground states imploring them to vote Democrat. If anything, this boosted the Republican vote, as random foreigners telling citizens who to vote for is not a good look.
At the risk of explaining a joke into the ground your comment has more than one reference. The UK's two main parties have their colors flipped. Labour's color is red.
Dems were red for longer on political maps than they have been blue. It was an odd quirk of CNN's maps in the 2000 election that made Democratic Party = Blue and Republican Party = Red in our minds. The fact that the map was everywhere for weeks while Florida was decided meant that it stuck instead of returning to what it had previously been for decades.
Oh we're the nutjobs? I suppose you'd like to have a fireteam of Marines just slamming Rip Its in your kitchen and digging burnpits to dispose of thier shit in your backyard? Yeah, crazy to not want that.
I think the nut job aspect would be leaping to the conclusion they would be forcing people to quarter these folks, as opposed to arranging long term hotels/rentals or maybe voluntary hosts. Employers do this all the time and people don't presume a constitutional crisis.
Still seems stupid, shouldn't need that much manpower to help canvas.
