More than a quarter million Muslims have become registered voters since the last presidential election, a Muslim group reported on Tuesday.

In June there were 824,000 registered Muslim voters whose first, middle or last names matched a list of 43,538 traditionally Muslim names, according to the Council on American-Islamic Relations, which used a private national database of voter information. That number represents a significant bump from the 500,000 voters the group accounted for in 2012, using the same method.
