Sen. Derrick Simmons (D - Greenville) eyeing higher office?

Sen. Derrick Simmons (D - Greenville) has been fundraising at a pace not normally seen by incumbents in safe seats (a description all observers would agree applies to him).  He hosted a well-attended fundraiser last month during the Blues Festival, and has another one scheduled next month.  Speculation obviously has arisen that Sen. Simmons is looking ahead to a run for higher office in 2015.  No word as to which seat he may be seeking, be it a Central District seat or statewide.
