The Wisconsin exit polls are bad news for Clinton
if this is a sign of things to come, as Obama continued to make
progress among several key demographic groups. Clinton's strategy
in Ohio and Texas is based on winning working class white voters
and women, but Obama won whites 52-46, those without a college
degree 54-45, and those with an income of less than $50,000 by
53-46. Among women, Clinton's edge was just 51-48. He also won
among every age group other than those over 60. As far as I can
tell, Clinton's base has now narrowed to elderly white women.
