I'm sure there's talk, but it's wishful thinking on the part of some.
Sheehan has not yet made a decision as to whether or not she's running. If she does, my guess is it's unlikely she will run on the SP ticket, but rather, will run an independent socialist unity campaign. If she announces before our convention, we might forgo our own candidate and endorse her. If she does it after we pick a candidate, we'll be running against her.
