Question

Why does Obama need Hillary's assistance with this Presidential campaign?

Answer 1

He needs those who supported her to win, although I think she has a surprise for him before the election.

Answer 2

Because Hillary can bring another couple percent of the voters to Obama. No other single person can do that for Obama or McCain.

Answer 3

he needs someone with brains by his side.

Answer 4

Actually you are wrong as a mink coat in the dead heat of summer. Senator Obama rises to the top on his own merit; with the support of the voters, not the Former First Lady, now Senator of New York.  

Answer 5

Well the Obama camp publicly plays down the number of diehard Clinton supporters and the fact that they wont vote for Obama to bring party unity because they understand that perceptions are everything.  If Clintons supporters all believe that all the others are voting Obama for party unity then the rest will follow, whether its true or not.

Answer 6

He needs her "All-American" persona to make up for his Anti-American persona that has come out.
