Yesterday, I ran into images like this, of people voting in New York. Here it's Queens, another was Staten Island. If anyone had the right to say "I can't vote today," it was these people, whose homes were ruined or who still didn't have power (etc), and whose usual polling locations were not functioning. I suppose some did decline. But many did not. They took time from rebuilding their lives to vote at last-minute tents set up for just that purpose.
If these people could manage to vote, none of the rest of us had an excuse not to do so.
