A new poll shows a slight change in the presidential race immediately following Wednesday night’s debate in Denver, with a 4-point lead for President Obama the day before the debate becoming a 1-point deficit the day after his uninspiring peformance.

On Tuesday, the Washington, D.C.-based Clarus Research Group surveyed 590 likely voters and found Obama leading Mitt Romney, 49 percent to 45 percent. On Thursday, Clarus found, in an identical number of interviews, that Romney had inched ahead by 1 point, 47 percent to 46 percent.
