(CNN) - The number of Muslims in the United States is tiny – less than one in 100 Americans – but their votes could sway the results of the presidential election in November, a new study says.
That's because they are concentrated in a number of key swing states, says Farid Senzai, the author of the report.
Take Florida, for example, the state that famously swung the 2000 presidential election for George W. Bush over Al Gore.
Bush won by 537 votes – while a get-out-the-vote phone bank contacted 23,000 Muslims in one day during elections in 2008 and 2010, the report says.
Nauman Abbasi – the head of Emerge USA, which ran the phone bank – says efforts like his will increase Muslim voter turnout.
There are about 1.2 million registered Muslim voters in the United States, according to the study, "Engaging American Muslims."
More religious Muslims and those more involved in their mosques are more likely to vote, it found.
