Trying to figure out exit polls

The exit polls from Fox, CNN and MSNBC are offering some early insights into how Wisconsin voters cast their ballots.
But, exactly what, is to be determined.
Among the findings:
-- Sen. Hillary Clinton and Sen. Barack Obama are splitting the lower economic vote.
-- 57 percent of Clinton voters would be happy if Obama is the nominee. 43 percent of Obama supporters feel the same.
-- 27 percent of voters in the Democratic primary identify themselves as independent.
