Poll shows Clinton with battleground leads

Hillary Clinton leads Donald Trump across the board in a new poll of battleground states.

According to Ballotpedia's battleground poll, Clinton leads Trump:
51% to 37% in Florida

45% to 41% in Iowa

50% to 33% in Michigan

48% to 38% in North Carolina

46% to 37% in Ohio

49% to 35% in Pennsylvania

45% to 38% in Virginia

Her leads held at nearly the same margins when Libertarian Party nominee Gary Johnson was included in the poll. And Clinton led Trump 48% to 37% when all states were factored together. With Johnson included, Clinton led Trump 44% to 34%, with Johnson at 13%.

Amid long-shot efforts by a handful of delegates to name someone other than Trump as the GOP nominee, Ballotpedia also polled Clinton against Ohio Gov. John Kasich and House Speaker Paul Ryan. Kasich had a slight lead on Clinton and Ryan polled neck-and-neck.

Separate polling in three battleground states, conducted by Quinnipiac University, found a much tighter race: Clinton up 8 points in Florida, but only 1 point in Pennsylvania and a tie in Ohio.

Ballotpedia surveyed roughly 600 voters in each of the states between June 10-22 for the poll and each survey has a margin of error of plus or minus 4 percentage points.

A Quinnipiac University national poll released Wednesday shows Hillary Clinton leading Trump by just two points, 42% to 40%, a much closer race than other recent surveys have shown. With third-party candidates included, Clinton leads 39% to 37%, with Libertarian Party nominee Gary Johnson at 8% and Green Party candidate Jill Stein at 4%.

This Quinnipiac poll is quite different from other recent surveys on the presidential race, showing a much tighter contest than others. Its field period overlaps with those of the Washington Post/ABC News and NBC News /Wall Street Journal polls released Sunday, both of which found Clinton significantly ahead of Trump.
