The Reuters/Ipsos tracking poll shows President Obama regained a narrow lead over Mitt Romney despite the attention of the Republican National Convention, 44% to 43%.
Romney was ahead by one point on Friday and two points on Thursday.
Said pollster Julia Clark: "This wasn't a lightning bolt convention. Comparatively speaking, this was a more muted convention in general... So it doesn't surprise me that (the bump in polls) wasn't a great deal bigger."
