TAMPA, Fla. (AP) - Bill McCollum and Rick Scott don't like each other, and they're showing it more than ever.

Rather than discuss issues, the Republican candidates for governor stepped up their attacks on each other in their second televised debate Thursday night.

McCollum, the state attorney general, was aggressive in hammering Scott for his leadership of a huge hospital corporation that ended up paying a record fine to settle Medicaid/Medicare fraud charges.

Scott repeatedly characterized McCollum as a desperate career politician who is behind in the polls and will say anything to get elected.

Scott jumped into the race in April and has since spent at least $25 million of his own money blanketing the state with TV commercials.
