If you're eligible to vote but aren't registered yet, watch out. They're coming to get you!
Campaigns, political parties and interest groups are all mounting massive voter registration campaigns this year to influence the outcome of the November elections.
The target is the millions of Americans — the Pew Center on the States estimates that number is 51 million — who are eligible to vote but not registered. The belief is that even a relative few of these voters could swing the election results.
