Latest Swing State Polls: Donald Trump, Hillary Clinton Battle For New Hampshire, Wisconsin, Ohio, Colorado

The campaigns of Democratic presidential nominee Hillary Clinton and her Republican counterpart, Donald Trump, were set Monday to make a last-minute push for votes in battleground election states.

The Clinton camp was busy looking to lock up New Hampshire, sending former President Bill Clinton to stump for his wife at Keene State College and Dartmouth College in Hanover on Monday. Trump, meanwhile, was set to appear in Green Bay, Wisconsin.

With just about 22 days left until Election Day, the candidates are narrowing their focus to the states that remain close, such as Wisconsin and New Hampshire, in an attempt to secure electoral votes. The national polls have shifted toward Clinton, with the Real Clear Politics average of polls showing her 6.3 points clear of Trump in a four-way race.

In New Hampshire, however, Clinton's lead is more than two points smaller than her national edge. The Real Clear Politics average for the state has her up 3.6 points, and the most recent local survey from WBUR showed her leading by just 3 percentage points. Libertarian Gary Johnson has seemingly wrestled away a fair number of votes in the state, polling at 11 percent in the WBUR survey.

Trump's visit to Wisconsin Monday could be a desperate attempt to take the state from Clinton, who leads by 6.7 percentage points in a four-way race, according to the Real Clear Politics average. The latest poll from Marquette University, carried out Oct. 6-9, had the former secretary of state 7 points ahead.

Trump's chances look better in Ohio, however. The latest survey from NBC News/Wall Street Journal/Marist showed Trump leading Clinton by one percentage point, 42 percent to 41 percent, among likely voters in the state. The Real Clear Politics average of polls still has Clinton up by 1.6 percentage points in the state in a four-way race.

But after that sliver of good news for Team Trump, it's more undesirable numbers in Colorado, where Clinton leads an average of 9 points, according to Real Clear Politics. Trump did score a minor victory in the latest Gravis poll conducted Oct. 12-13, which showed Clinton leading by 5 percentage points, a far narrower margin than other recent surveys that showed her up by as much as 11 points.

Using this slew of good polling for Clinton, the polls-only election forecast from data-driven website FiveThirtyEight was giving the Democratic nominee an 87.2 percent chance of winning the election as of early Monday morning. On a state level, the polls-only forecast gave Clinton an 84.9 percent chance of winning New Hampshire, 89.9 percent for Wisconsin, 66.2 percent for Ohio and 87.7 percent for Colorado.
