Larger lessons? It’s always dangerous to see too big a trend in off-year elections. But there might be one for Democrats: You are on your own. Barack Obama’s popularity–or his political operation–do not transfer when he is not on the ballot. This election could make Democrats more attuned to the political rhythms of their home states, and less willing to take risks. And that’s not necessarily good news for efforts to bring moderates aboard President Obama’s biggest initiatives, starting with health reform.
