Florida voters are split on gay marriage and oppose legalizing marijuana, according to a state poll released Thursday. The survey by Quinnipiac University of 1,261 registered voters found that 45 percent oppose gay marriage while 43 percent support it. That's a change from last May when 50 percent opposed same-sex marriage. The poll's margin of error was plus or minus 2.8 percent. Fifty-two percent are opposed to making marijuana legal while 42 percent say the drug should be made legal. The states of Washington and Colorado recently legalized small amounts. On other issues: 73 percent of voters said they oppose an effort to allow colleges like the University of Florida and Florida State University raise tuition higher than the law currently makes possible. Gov. Rick Scott earlier this year vetoed a bill that would have let the state's two top research schools exceed an existing 15 percent annual cap on tuition increases. But new House Speaker Will Weatherford has already voiced support for bringing the measure back during the 2013 session of the Florida Legislature.
