MAP: Track campaign stops by Democratic, Republican presidential tickets

With most states reliably red or blue, the path to the 270 electoral votes needed to win the presidency runs through seven states where the contest is expected to be narrowly decided.

Those are: Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin. All together, they are home to only 18.3% of the country’s population.

The Associated Press has been tracking the campaign appearances of the Democratic and Republican tickets since March.

Since then, Pennsylvania has been getting the most love from both campaigns, with a total of 21 visits, including one planned this coming weekend. Wisconsin and Michigan are close behind with 17 and 16, respectively.

Most states haven’t been visited at all, and a handful with clusters of wealth, such as California, get attention not for their voters but when the campaigns want to tap the wallets of the rich.
