The YouGov/CBS News 2016 Battleground Tracker polled likely voters across eleven competitive states before and after the Republican National Convention
Donald Trump has made small gains among undecided voters in eleven competitive states, according to two waves of the YouGov/CBS News 2016 Battleground Tracker, carried out before and after the Republican National Convention.
The Republican nominee’s share of support has risen to 42% in the latest survey, putting him one point ahead of his Democratic challenger Hillary Clinton. Trump’s support is up from 40% in the previous round of interviews while Hillary Clinton’s support held firm at 41%. Gary Johnson’s support is 6%, a one point increase from before, and Jill Stein’s was unchanged at 2%. The share of remaining undecided or third-party voters fell from 11% to 9%.
The study includes likely voters from eleven states: Colorado, Florida, Iowa, Michigan, North Carolina, New Hampshire, Nevada, Ohio, Pennsylvania, Virginia and Wisconsin. Voters who participated in the most recent wave were first interviewed July 13-15 and were recontacted July 22-23 at the conclusion of the Republican National Convention.
Overall, thirty-six percent of likely voters in these states report feeling more positively about Donald Trump following the convention, while 32% report feeling more negatively. 22% say their views are unchanged.
The most recent wave of interviews were conducted July 22-23, 2016 for the CBS News 2016 Battleground Tracker. A detailed description of the methodology used to carry out the surveys can be found here.
