Omaha investor Warren Buffett, who appeared with Clinton, is promoting an effort to drive people to the polls and pledged to personally drive some himself.

Lewis lives just a block away from North High. She’s for Clinton. Had she felt able to stand in the long, hot line, she would have seen Clinton in person. Instead, Lewis had to be content with watching on TV.

But she had that Black Votes Matter sign, and she hoped that neighbors and passers-by would get the message, one that is both an admonition and a plea.

The messenger is Preston Love Jr., a north Omaha political organizer who made and distributed some 1,500 of those signs, which you can see sprinkled in the yards and front windows of northeast Omaha. Love is well aware that he needs that message to take hold beyond the voting faithful, like Lewis.

Love has to convert a more doubtful demographic — younger would-be voters. They may not have firsthand experience of the value of voting. And they tell him that they feel cut out of the process and even stressed out by everyday life.
