It is all the process, last time it was all over by the Fla primary. I dont see what the hurry is. A few more will be whittled down by the Iowa State Fair Straw poll.
Sarah doesnt have to come in till Labor Day, if she wants.
Agreed, and I think Sarah well understands this. Look at the circus going on in the Republican field right now. Why would she want to be anywhere close to that melee?
If, as you say, she waits until Labor Day to announce, there's still about six months of solid campaigning to do until the primary vote in Feb - March of 2012.
There's plenty of time yet, for her to announce.
