Pres. Barack Obama visited Chicago Sunday, to encourage Illinois residents to vote, and to do it early. Early voting begins today, and runs until just before election day. That could change campaigns' strategies, or expand the electorate.
It used to be that campaigns geared up for one day: Election Day. Starting in 2006, Illinois residents were given the option of casting an early, in-person ballot. That used to last for a two-week span. Not this election. Voters have from today until Nov. 2 to vote early.
Look for people to take advantage of it.
