Clinton overtakes Obama by point in Gallup poll
 A day after one national poll showed Senator Barack Obama (D-IL) taking a twenty-point lead over rival Senator Hillary Clinton (D-NY), another one shows a nearly three touchdown difference, an apt metaphor for this extended topsy-turvy campaign season.
Friday's Newsweek poll, which polled Republicans and Democrats, showed Obama with 54 percent over Clinton's 35 percent.
However, Gallup continues to show a very tight race, even if Clinton has very slim odds of winning, with just the superdelegate race at stake.
"Gallup Poll Daily tracking shows that Hillary Clinton now receives 46% of the support of Democrats nationally, compared to 45% for Barack Obama, marking the first time Obama has not led in Gallup's daily tracking since March 18-20," Gallup noted Saturday.
Gallup adds, "These results are based on interviewing conducted April 16-18, including two days of interviewing after the contentious Wednesday night debate in Philadelphia and the media focus that followed. Support for Hillary Clinton has been significantly higher in both of these post-debate nights of interviewing than in recent weeks. The two Democratic candidates are now engaged in intensive campaigning leading up to Tuesday's Pennsylvania primary and are under a continual and hot media spotlight, increasing the chances for change in the views of Democrats in the days ahead."
Although, as opposed to the Newsweek poll, Gallup only polled Democrats, it's latest national poll also shows Clinton with one more percentage point of support than Obama.
"There has been no change in the general election trial heats, with Obama's margin over Republican John McCain at 45% to 44% among registered voters nationally, and Clinton's margin at 46% to 44%," Frank Newport writes for Gallup.
