(CNN) - Hillary Clinton's Pennsylvania win last Tuesday has clearly given the New York senator a boost in the national polls, the latest daily tracking survey from Gallup suggests.
Clinton and Obama are now dead even at 47 percent among likely Democrats, according the newly released numbers. That number remains unchanged from a tracking poll released Saturday and represents a 5-point gain for Clinton since her Pennsylvania win.
In a similar tracking poll released the day of the primary, Obama led Clinton by eight points, 50-42 percent. The Illinois senator's lead over Clinton reached a high of 11 points on April 14.
Meanwhile, a Newsweek poll released Saturday also shows gains for Clinton, but finds the New York senator continuing to trail Obama. In that poll, Obama holds a 7 point lead over Clinton. That margin is more than half of the 19 point lead Obama held in a similar Newsweek poll taken shorlty before the Pennsylvania primary.
Recent polls also show the two candidates locked in a dead heat in the crucial state of Indiana, which votes May 6. In a CNN "poll of polls" released Friday, Clinton and Obama both register 45 percent support from likely Democrats in the Hoosier state.
Since Obama is favored to win North Carolina - the other major prize May 6 - some Clinton advisers have said the New York senator must score a victory in Indiana remain a viable candidate.
