Various problems, but no major malfunctions, have been reported at polling places around the country on Election Day.
Malfunctioning voting machines, long lines, confusion over identification rules and misleading phone calls and fliers were reported in Ohio, Pennsylvania, Missouri and Florida, among others.
Some polling places in Ohio had to dispense with troublesome electronic voting machines and switch to paper ballots.
And in Missouri, some voters report being asked to show photo ID, even though the law requiring photo ID at the polls was struck down by the courts.
