What in tarnation is she waiting for?
In order to win the nomination, she has to outwit and outmaneuver them.
The longer she delays announcing her candidacy, the longer she keeps the ruling-class RINOs, state-controlled media, DemocRAT and Republican opponents, etc. in complete and total disarray.
Why should she give up her strategic advantage?
To make it "fair" for the RINOs and 'Rats?
Palin is coming, and the Tea Party is coming with her.
Probably for Perry to stumble just enough that Perry supporters, will need to start focusing some of their spin, against Romney.
Just trying to help. :)
