President Barack Obama and presumptive Republican nominee Mitt Romney are deadlocked in three key presidential battleground states, according to a new round of NBC-Marist polls.
In Iowa, the two rivals are tied at 44 percent among registered voters, including those who are undecided but leaning toward a candidate. Ten percent of voters in the Hawkeye State are completely undecided.
In Colorado, Obama gets support from 46 percent of registered voters, while Romney gets 45 percent.
And in Nevada, the president is at 48 percent and Romney is at 46 percent.
These three states are all battlegrounds that Obama carried in 2008, but George W. Bush won in 2004.
"These are very, very competitive states," says Lee Miringoff, director of the Marist College Institute for Public Opinion, which conducted these polls. "Everything is close."
Results from NBC-Marist polling in three other battleground states released last week – Florida, Ohio and Virginia – showed Obama with narrow leads in each state.
Optimism, pessimism and enthusiasm
In Colorado, Iowa and Nevada, a more optimistic attitude about the U.S. economy is working in Obama's favor. Majorities in each of the three states believe the worst is behind us, rather than yet to come.
In addition, majorities in these states say that the president mostly inherited the current economic conditions.
