While in principle only U.S. citizens can vote in this country, in Rhode Island proof of U.S. citizenship is not required to register to vote. Our secretary of state’s Web site, www.sec.state.ri.us/elections/voting/register/documentstoregister.html, indicates that “documents” are required for first-time voters to register. None of the documents or other “identification” listed provides proof of U.S. citizenship.

Since this is apparently a longstanding constitutional violation, proper re-registration of all currently registered voters should be required immediately. Otherwise the results of future elections will be invalid if, in fact, non-citizens have been registered to vote.
