Assumption: This blog entry is written with the assumption: if a campaign puts in the time & money to have a chance of winning an election, the top priority should be winning the election (while complying with constraints like following the law & respecting the ethics of the candidate/campaign leadership).
If the goal of a campaign is to get the most votes, the campaign should push its supporters to vote early.
On November 4, 2014 I was reminding people to vote in a working class neighborhood in Chicago's Ward 45. There were plenty of people who didn't vote, most of them, women. It was a caretaker who couldn't leave her husband. It was a student whose father seemed like a Rauner supporter. It was a mother with work obligations.
Losing elections sucks. And progressives lose elections because regular people don't vote. Early voting reduces the problem of regular people skipping elections.
In Chicago, there are two ways to vote early: in person and by mail.
Voting by mail is on paper. Voting early in person is on a machine.
There is a small group of activists--who hold themselves out as experts--who are adamantly opposed to voting on machines.
