MIAMI (AP) — Former President Bill Clinton is starting a two-day Florida campaign trip for President Barack Obama with a speech at Florida International University.

The Obama campaign says the appearance Tuesday at the Miami university will focus on economic issues. Clinton is set to make another appearance on Wednesday in Orlando.

Florida is one of a handful of swing states considered key to deciding the election between Obama and Republican nominee Mitt Romney. Obama himself spent two days over the weekend campaigning in Florida. Florida has 29 electoral votes and Obama carried the state in 2008 over John McCain.

Democrats say turnout is one of the keys to winning the Nov. 6 election. South Florida's three heavily-populated counties of Miami-Dade, Broward and Palm Beach include many reliable Democratic strongholds.
