If you lose your house due to foreclosure, you no longer live at the address you listed on your voter registration. Where then can you vote? Or more ominously, do you lose the right in a pragmatic sense? Can your vote be successfully challenged? From an editorial in todays NYT:
The foreclosure crisis could do considerable damage to the nation’s voting system. More than a million people have lost their homes in the past two years. And because voter registration is based on people’s residences, they could face politically motivated challenges at the polls.
