The Huffington Post: Despite What Trump Says, It’s Not Illegal To Be Registered To Vote In Multiple States
Gerry Hebert, director of voting rights and redistricting at the Campaign Legal Center, said duplicate registrations usually were clerical errors.
“It’s a matter of election administration (or lack thereof) when someone moves and their former voter registration office never gets informed by the new voting registrar,” Hebert said in an email.
“Voting in the same election twice would be a crime,” Hebert observed. Being registered in two places is not.
