She is seven months’ pregnant right now, I would not put any stock in the suggestion that she may be on the ticket.
She'll have the baby (God willing) in May. Even with 2 to 2.5 months of downtime she can get to campaigning at the start of August. My hunch is that Gov. Palin campaigning for 3 - 3.5 months beats the tar out of any given Dem or RINO campaigning for 5 months.
Of course, I'm a bachelor without kids who supported Fred "let's not be hasty about this" Thompson, so what the heck do I know.... ;-)
The more likely probability is that she'll get a prime spot speaking at the convention to set up her future in the party. The GOP sure needs a big dose of Palin - or something like her - in the arm right this instant.
