here are three things I'd keep quiet about with regard to Sarah Palin.
(1) How can she do her job as vice-president and take care of her kids? Which leads to the question, how can Obama do the much more demanding job of president and take care of his kids?
(2) What makes anyone think that Palin has enough experience to be "one heartbeat from the presidency?" Which leads to the question, what makes anyone think that a one-term Senator from Illinois who has been running for president for most of his term has enough experience to actually be president?
(3) Is Sarah Palin's church/pastor nutty? Which leads to such an obvious question that I won't bother raising it!
In short, it strikes me that Obama's allies may be succeeding at discrediting Palin to some extent, but only at the expense of undermining Obama. Even if raising such questions undermines Palin more than it does Obama, even much more, given how many people vote based on the top of the ticket versus based on the bottom, this is hardly a winning strategy.
