I have been remodeling the house and most of the workers are hispanic, most have been here in US for several generations. NONE Of them like Obama. One even said if Obama wins he will meet the same fate that JFK did. He was NOT threatening him, just stating what he thinks would happen.
Your demo graphics are probably correct. Consider, tho, that Jewish & Hispanic Dems are not going to vote for the R nominee, either. If they sit it out (hihgly likely) the tide will be turned on the huge increase of the black vote.
Young liberal feminists are a very small bloc and would not be able to carry an election. Truthfully, the middle-aged feminists (they have money and networks and are a significantly larger bloc!) would be upset if the haggard and crusty Hillary beats the suave and sexy Barak.
