While Zobgy stayed at 7% in favor of Barack today, Rasmussen tightened a bit.

The Rasmussen Rasmussen Reports daily Presidential Tracking Poll for Friday shows Barack Obama with 51% of the vote, John McCain with 47%.
Over the past five days, Obama's lead has been between three and five percentage points each day. That's a bit tighter than the four to eight point margins enjoyed by the Democrat for the previous month (http://www.rasmussenreports.com/public_content/politics/election_20082/2... http://www.rasmussenreports.com/public_content/politics/election_20082/2008_presidential_election/favorable_ratings_for_presidential_candidates" target="_self">see trends).

The tightening comes entirely from McCain solidifying his support. The Arizona Senator has reached the 47% mark on two of the past three days. Prior to that, he had not reached the 47% level of support in over a month. Another way of looking at it is that McCain's support has now stayed at 46% or above for five straight days. Prior to that, McCain had only reached the 46% level four times in a month.
However, while McCain has been solidifying support, Obama has not lost ground.This is the 36th straight day that Obama’s support has been between 50% and 52%.
