Representing parts of Hillsborough, Manatee and Pinellas counties, Sen. Arthenia Joyner, D-Tampa, looked vulnerable at the end of the first quarter of 2010. She had only raised more than $44,000 and spent more than $20,000 of that. Yet, despite the unimpressive fund-raising, Joyner is headed back to the Senate for a second term without any November opposition.
