LEE COUNTY, Fla.- State election officials say nearly 4.5 million Floridians have already voted. The numbers were released as Florida's Democratic party filed a lawsuit to extend early voting. An estimated four out of 10 voters overall will have cast their ballots early, but both Mitt Romney and President Obama are counting on a big election day turnout.

In Southwest Florida, 52,000 voters fought the long lines to cast their ballot early in Collier County and more than 50,000 have already voted in Lee.

Democrats filed a lawsuit demanding an extension of available time. This stemmed from a decision last year by the state to reduce the number of early voting days from 14 to eight, but Florida's Democratic party says that's not enough. It filed the lawsuit seeking more voting time in Broward County, Palm Beach and Miami-Dade counties, where balloting didn't wrap up until early Sunday morning.

Lee County Democrats stand behind the decision.

It's not clear what remedy there could be before election day tomorrow.

If you have decided to wait and vote tomorrow, make sure you bring your photo ID and remember to check your precinct on your voter registration card. A lot of those have been shuffled since the last Presidential election.
