Will you be able to vote Tuesday? Despite Sandy, probably.
Many electronic voting machines -- used now by two out of every five counties nationwide, according to the Voting Technology Project -- often require consistent power to work for the long hours they are needed on Election Day, even though some have battery power.
If electricity remains out in some areas next Tuesday, those areas may have to scramble to find alternatives, including paper ballots.
It is unlikely voters in the hardest hit states will be given an extension if they cannot access polls, despite damage from the storm.
Only Congress can change Election Day, according to an 1845 law. If it opts to alter the timetable -- something never previously done -- every state would have to be included.
The same law also says that if a state "shall fail to make a choice" on Election Day, then electors to the Electoral College may be appointed on a "subsequent day" as determined by state law.
