That, and (not that anybody's listening, certainly not guilty parties that I know of): if you want Obama to win, lay OFF Sarah Palin. Because every time people sneer at her, or mock her accent, or her outdoorsiness, or her conservative Christian mom-ness, you reinforce the feeling that a lot of people have that you're laughing at them too.
That is "elitist" behavior (more properly: acting like you're culturally superior), and I fully sympathize with people who are turned off or offended by it. Hell, I'm turned off by it.
Also, shut up about whether she should be at home with the kids, and probably the safest thing to do is just not to mention Briston Palin's name.
Attack McCain, and emphasize, if you must, that she's so right wing she has to go in a full circle when she wants to turn left. But the last--THE LAST--thing to do is to allow this to turn into an argument about Obama vs. Palin. Because you just demoted the Democratic Presidential candidate.
