Tom Knox declares that he is still trying to decide about running for mayor

Tom Knox, a wealthy Philadelphia businessman who seems to crave media attention for political ambitions,declared Thursday morning that he will not run for governor in 2014 but may run for mayor in 2015.

"After careful consideration and many discussions with people whom I deeply respect, I am seriously considering a run for mayor of Philadelphia in 2015," Knox said via an emailed statement to reporters.

Knox finished second in the 2007 Democratic primary for mayor, ran briefly for governor in 2009 and 2010 and then toyed publicly for months with the idea of running again for mayor in 2011 as a Democrat or independent.

In February, Knox issued a news release saying he had a "serious intent to mount another campaign for political office."  He just didn't know which office.

Knox, who would certainly face a crowded Democratic primary race for mayor, on Thursday promised a "formal announcement of my plans in the very near future."
