...
Asked which candidate would do a better job on the economy, respondents in Colorado (45 percent to 42 percent) and Iowa (46 percent to 41 percent) picked Romney over Obama. But the two men were tied in Nevada (44 percent to 44 percent).
The NBC-Marist poll also shows that Obama’s approval rating is above water in Iowa (46 percent approve, 45 percent disapprove), and it’s underwater in Colorado (45 percent to 49 percent) and Nevada (46 percent to 47 percent)
And in Nevada’s competitive Senate contest, the survey finds incumbent Republican Sen. Dean Heller in a tight race with Democrat Shelley Berkley, with Heller getting 46 percent among registered voters and Berkley getting 44 percent.
These NBC-Marist polls were conducted May 22-24 by landline and cell phone of 1,030 registered voters in Colorado, 1,106 registered voters in Iowa and 1,040 registered voters in Nevada. The margin of error in all three surveys is plus-minus 3.0 percentage points.
