Scott has issued dire warnings about the storm and ordered evacuations of 1.5 million people in the state. Forecasters warn that if the storm makes landfall, its impact could be historic.
Earlier the Clinton campaign had called for an extension of the Oct. 11 deadline in light of the storm.
"The voter registration deadline in Florida is October 11th and our hope would be that a little bit more time will be given for people who were expecting to be able to get registered before the election and we certainly expect that the governor and local officials will make that possible," said Clinton campaign manager Robby Mook.
Mook also said that the campaign was focused on the safety of Floridians.
"Our first priority on Hurricane Matthew is that people are safe," he said. "We have been doing everything we can on social media and email list to make sure that all Floridians heed the warnings of public officials that are saying this could be a very deadly storm."
