Public officials, businesses, law enforcement are making plans to deal with potential election-related unrest as the president attacks mail-in ballots and has refused to commit to a peaceful transfer of power.

Surveys find an American electorate that's fractured and inflamed. On the president, for example, 87% of Republicans approve of Trump's handling

of the job, compared with just 6% of Democrats, according to Pew. 85% of Democrats say the

coronavirus is a major public health threat, while only 46% of Republicans feel the same way.

And three-quarters of Democrats say the way people of color are treated in the

criminal justice system is a very big problem compared with 20 percent of Republicans. Is there

historical precedent for such a deeply divided electorate? We look at moments when the nation felt
