Tomorrow evening we get our first look at how politically motivated citizens are turning out for the various candidates for president. "Politically motivated" in Iowa requires more of a commitment than elsewhere, there is no mail balloting or dropping by to cast a ballot, one has to attend and stay awhile.
Iowa's population is roughly 3.1 million and the average turnout for presidential year caucuses totals 120,000 "politically motivated" people. That "eyeballs" at about 4% of the state's small population. If the turnout is higher, say 180,00, it is supposed to be good for Trump ... we'll see.
