After the Republican Convention, Donald Trump got a small bump which put he equal to Clinton in the battleground states (Colorado, Florida, Iowa, Michigan, North Carolina, New Hampshire, Ohio, Nevada, Pennsylvania, Virginia, and Wisconsin). But Hillary Clinton has regained that lead after the Democratic convention.
The chart was made from a new CBS News / YouGov Battleground Poll -- done on July 29th and 30th of 2,211 likely voters in those battleground states, with a margin of error of 2.6 points.
