People are far too willing to read entrails and believe she is either running or not and people seem to stand fiercely by their convictions either way, evidence notwithstanding.
Palin is doing the things people do when there’s more than a year before an election and they might want to be “official” candidates. To me, that means she’s “running.” If she has to have some lame press conference to announce it before it meets your definition, then she’s not. Whether or not she gets to that point depends on what kind of support she finds. But looking for support like that is “running” to me.
