Iowa doesn't permit busloads of outsders to interfere in their caucus.
WTF? You are saying there are no outsiders particpating in the campaigning, or canvassing of Caucus voters up to the day of said caucus? Shit, every candidate literally brings armies from out of state trying to help make their cases.
Just for S & G's call the larger cities' Chambers of Commerce to get data of resteraunt and hotel occupation in the days and weeks leading up to the caucus, and get back with us.
Again..... There is pretty big difference in Webster around the words...... "Participate" and "Vote". Your silly Trump Love has fried your mind.
