Announcing for POTUS won't make it happen by magic either...though it may extend the shelf life of brand Palin a bit.
Especially when Palin has decided not to establish the professional campaign and financing infrastructure needed to get her message out beyond her extremely loyal followers that, according to the latest polls, constitute approximately 11% of the GOP voters.
If Palin does announce, it seems that the game plan will be more "Preaching to the Choir" with the same results.
An undecided Independent voter is not going to dish out $4.79 for the privilege of watching "The Undefeated" on Pay-per-View.
With the recent polling, Palin is no threat to the two leading GOP primary front-runners but the "Palin Thing" is having a negative effect on the psyche of her 11% of the GOP with potentially very destructive consequences in the effort to defeat Obama in the general election.
Already, you hear talk of boycotting the general election or writing in "Palin" in the general election if Palin is not the GOP nominee. As a Palin supporter posted on Free Republic a couple of days ago, "If Sarah does not get it, Obama can have it."
