Another poll was released Wednesday showing President Obama and presumptive Republican presidential nominee Mitt Romney in a virtual dead heat among nationwide voters.
The daily tracking poll by Rasmussen Reports shows Mr. Obama with support from 46 percent of voters and Mr. Romney at 45 percent, with 4 percent preferring a third candidate and 5 percent undecided. A flurry of polls have come out in the past week showing the two major-party candidates as virtually tied in popular votes with Mr. Obama leading in most cases by 1 or 2 points.
The latest poll follows The Washington Times/JZ Analytics survey released Sunday that showed the race is deadlocked.
That poll had each candidate with 45.7 percent support.
Other recent polls from Gallup, Fox News, ABC News and the Washington Post have showed Mr. Romney with 1-point leads.
The Rasmussen poll showed that the president has predictably seen some of his strongest support from voters younger than 30, who favor him by a 35-point margin. Mr. Obama won the demographic by 34 points in the 2008 presidential election.
Mr. Romney, however, leads by 21 points among senior citizens, who favored 2008 GOP presidential nominee Sen. John McCain by just 8 points that year.
Another poll released Wednesday by the firm found that while Democrats and Republicans rely heavily on their national conventions to help boost their candidates’ profiles, nearly half of voters consider the events to be a waste of money.
The poll showed that 44 percent of likely voters say the conventions are “a waste of time and money,” while 35 percent disagree and 22 percent are undecided.
