Is the Obama Factor good?

The marriage protection amendment in Calif. may depend on turnout. And that turnout may be affected by the Obama factor. He will draw out the black vote to get him elected (a good thing), but blacks -- even black Democrats -- are fiercely homophobic and drawing them out will increase the chances the amendment will pass. Yet we may need all those black voters because the amendment will also draw out the GOP vote. What a bind! Which means Obama has to be very careful how he talks if he is against the amendment (he hasn't said yet).
