If either nominee dies or withdraws before the Nov. 3 election, his party —  @DNC or @GOP — has to designate the replacement. But whether there& #39;s enough time for that nominee to get on the ballot is … up to the states.

Given that 29 states have already begun mailing ballots to voters, this could be a big legal mess, tied up in state and federal courts. Then there& #39;s the Electoral College …

Some states prohibit electors from casting ballots for anyone other than the person who won that state’s popular vote. If those electors were to choose their party& #39;s new nominee (instead of the dead/withdrawn candidate), that could also … end up in the courts.
