Agreed on the Palin part. Personally, I think that this VP selection made for great political tactics but betrayed a lack of true statesmanship, which may well prove crippling. The only question is whether it will prove crippling before the election, or (worst case) after.
The secret to politics I think is easy to articulate but hard to achieve - it is to position your candidate so that the attacks on him or her merely make them stronger, vote-wise. Conversely, one’s opponent should be so placed that speaking to his or her strengths weaken them with the public. The extreme form is “swiftboating”, but that implies dishonesty - these tactics can be achieved without overt lying.
Take Palin vs. Obama (and it is odd to even think of them as the opposites, but that is how the election is shaping). Palin has endured many in some cases quite justified attacks on her competence, knowledge, ethics, family choices and morality; all of which to an extent feed into her “I’m just like you, gosh darn it” pose. Her true weakness - the fact that her policies, to the extent that they are known, are such as to only appeal to a minority of the truly right wing “base” - get lost in a mass of irrelevance. The attacks, even though they are in many cases justified, seem to strengthen her, not weaken her. Compare her presence in the election to poor Biden - one may say, “Biden who”?
Similarly, Obama’s strengths are his personal qualities, charisma, intelligence. Portraying these as “elitism” is, as a tactic, a way of taking them head-on - turning a strength into a source of weakness.
Or at least such is the Republican narrative.
The difficulty for the Democrats is that, from what I’ve seen so far, they don’t seem to have a really good handle on how to counter that narrative. Going on about how dumb the majority of the public is a la Stevenson (or worse yet, jealous and vengeful) merely strengthens it.
I would guess you are 100% correct about the author’s motives for writing the article. That does not mean, however, that she does not make good points nonetheless. If the Democrats lose this election, it will I think be because they failed to solve the problem I have outlined.
