Clinton has distinct organizational edge

Ohio is a must-win state for Donald Trump; a loss would almost certainly deny him the presidency and secure the White House for Hillary Clinton.

Trump and Clinton have a good chance here of stealing the other party's voters.

Clinton is going after Republican-leaning suburbanites put off by Trump and is trying to persuade blue-collar white voters that he is a hypocrite on trade and business issues.

Trump has set his sights on blue-collar Democrats with a campaign heavy on expressions of grievance for decades of manufacturing declines. He's also courting Republicans eager for change after two Democratic White House terms.

"Both campaigns are probably spending time watching some of their traditional voters run away and watching others run to them," said Doug Preisse, a confidant of Gov. John Kasich who heads the GOP in Franklin County.

The most recent public polling has the race dead even. "It's winnable for both candidates. The question is who has the superior ground game and strategy," said David Paleologos of the Suffolk University Political Research Center.

Organizationally, Clinton has the upper hand. Her team barely left after the March primary. Trump's campaign has been slower to form, a danger in a state where early ballots can be cast starting Oct. 12.
