What goes up must come down, but how quickly the might Obama has fallen.

From Rasmussen Reports:

The Rasmussen Reports daily Presidential Tracking Poll for Friday shows that 30% of the nation's voters now Strongly Approve of the way that Barack Obama is performing his role as President. Thirty-eight percent (38%) Strongly Disapprove giving Obama a Presidential Approval Index rating of -8.

Just 25% believe that the economic stimulus package has helped the economy.

The Presidential Approval Index is calculated by subtracting the number who Strongly Disapprove from the number who Strongly Approve.

Overall, 49% of voters say they at least somewhat approve of the President's performance. Today marks the first time his overall approval rating has ever fallen below 50% among Likely Voters nationwide. Fifty-one percent (51%) disapprove.

Eighty-three percent (83%) of Democrats continue to approve of the President’s performance while 80% of Republicans disapprove. Among those not affiliated with either major party, 37% offer a positive assessment. The President earns approval from 51% of women and 47% of men.
