Can he do it? Yes he can! -- In a state in which nearly 9 in 10 Democratic voters are white, Obama won more than 6 in 10 of the votes of white men.

From The Washington Post:

After the Super Tuesday primaries two weeks ago, Sen. Barack Obama faced continuing questions about the support he could draw from lower-income white voters and those with less education, who had to that point proved to be the bedrock of support for Sen. Hillary Rodham Clinton.

But yesterday the senator from Illinois broke deep into Clinton's base in Wisconsin. He solidified gains he made in last week's Potomac Primary, proving competitive among some key Wisconsin voting blocs that had been backing the senator from New York and overtaking her among others.

In a state in which nearly 9 in 10 Democratic voters are white, Obama won more than 6 in 10 of the votes of white men, while Clinton held only a narrow edge among white women. And he defeated her by double-digit margins among those voters with family incomes less than $50,000 and among those without college degrees, exit polling shows.
