Chuck Devore's numbers appear to have INCREASED (slightly) since Governor Palin endorsed Fiorina.
I also believe the huge undecided (I think it was somewhere around 25-30%) broke for Fiorina after the Palin endorsement especially after she clarified that Campbell was a RINO.
I read this was one of the hardest decisions that Palin had to make but she saw that Devore was not gaining traction (until this last poll he had not garnered more than 16% of the vote)and that Fiorina had the best chance to stop Campbell.
And what many people still miss about the Tea Party movement (I did until a couple of months ago as well) is that the Tea Partiers are NOT rabid so-cons but actually more libertarian in orientation and more concerned about fiscal issues (deficit, taxes, budget, entitlements etc)than they are about abortion or gay rights or Afghanistan.
That Sarah Palin is the “star” of the TPM is a tribute to her eclectic political presentation that she is able to come off as a strong fiscal conservative to these folks without alienating them because of her strong view on pro-life and the role of the military in American life.
Sarah Palin is definitely not a one-trick pony as many of her critics would have you believe.
