I don't know about tricks, but Trump has SEVEN live events in IOWA from Saturday through Monday prior to the Hawkeye-Kawki at 7:00 PM.
If thousands of people wait for 3-9 hours in the cold, to get into a one hour speech, why would they not get into their warm car, drive to a known site, go inside, sit in the warm room, listen to some local neighbor pontificate for 20 minutes, cast a secret ballot {the pubbies ballots are secret} and go home.
Why is this Hawkeye-Kawki supposed to be so hard to do? I've been a poll watcher since 2000 and I go to the polling place before it opens at 8:00 AM and stay until the final envelopes are sealed and picked up at around 10:00 PM. That is being in a room with all demonRATs that hate my guts for being there so they can't openly and easily cheat. But with my little friends I know I'm as safe as can be. It is still a long day.
Opps, 7:00 AM.
