Played it safe in New Jersey today, never mentioned Obama's name.
Incidentally, as Noam notes below, a key Clinton campaign's talking points for why Florida should matter is the fact that an Obama national ad buy spilled into Florida. I'm trying to get someone in the Clinton camp to quantify the exposure for me. One Obama aide I spoke with on another topic didn't have numbers but downplayed the likely audience, saying the spots appeared on cable channels only.
