I caught a little of Sarah Palin's speech from last night. She did well, but then, it's not that hard to perform well on your home turf with thousands of your own cheerleaders.
I'm not a big fan of political conventions anyway. They're red meat for the party's base, and I'm not strongly affiliated with either of the major parties.
I want to see some debates. I know they're also somewhat contrived (what isn't, in a political race?). But they allow you to do window shopping with the choices side by side, and if the moderator and questions are halfway decent, you actually get some glimmer of insight into what the candidate is really like, or at least how they'll perform when someone is tearing into them under the spotlight.
I expect Obama and McCain to essentially ignore each other in the debates and stick to their talking points. Obama will probably float up on a little cloud talking about how he wants to make everything wonderful (I'm especially interested in how he handles questions about raising taxes, though...probably by deflecting with an answer about how Bush has put through tax cuts for the rich), while McCain seems more and more like a tortoise...slow and steady with a thick shell. I thought he looked limpid next to the other Republican candidates in the primary debates, but apparently the strategy worked.
I don't expect Biden and Palin to ignore each other. On the contrary, I think (and kind of hope) they'll go for each other's jugulars. If so, those will be fun debates to watch.
I still haven't completely made up my mind on who to vote for, though at this point I'm about 75% toward Obama. The political cheerleading of the conventions isn't going to push me one way or the other, though.
