Today's Rasmussen Tracking Poll:
The Rasmussen Reports daily Presidential Tracking Poll for Saturday shows that the bounce is continuing for Barack Obama. The presumptive Democratic nominee attracts 46% of the vote while John McCain earns 40%. When "leaners" are included, it’s Obama 49% and McCain 43%. Just four days ago, the candidates were tied at 46% (with leaners). Obama is viewed favorably by 57% of voters, McCain by 55%

More from Rasmussen:
Over the coming week, it will be interesting to see if the bounce continues. It is possible that Obama could open an even bigger lead and move above the 50% level of support. That would be significant both in the context of this campaign and historically. Since Abraham Lincoln was elected as the first Republican President in 1860, the only Democrats to win the White House with a majority of the popular vote have been Franklin D. Roosevelt, Lyndon B. Johnson, and Jimmy Carter.
