Runners leave the Supreme Court in Washington with papers announcing court decisions, June 20, 2016. The Supreme Court is set to begin its new term as it ended the last one, down one justice and ideologically deadlocked on a range of issues.

As Americans prepare to cast ballots for the next president, the voting process has never been more convoluted. A federal appeals court over the summer struck down several parts of a North Carolina law that not only required voters to show photo ID but also reduced early voting and eliminated same-day registration during the early voting period.
