Donald Trump continues his surge in the state polling. Breitbart-Gravis released a series of polls on Tuesday. The race in blue state Minnesota is tied up at 43 to 43.

Breitbart.com reported:

Three Breitbart/Gravis state polls of likely voters — Minnesota, Pennsylvania, and North Carolina — demonstrate how close the presidential election between Democrat Hillary R. Clinton and her GOP rival Donald J. Trump has become just before the first presidential debate.

In Minnesota, Clinton and Trump are tied with each having 43 percent of the vote, said Doug Kaplan, the managing director of Gravis Marketing, the Florida-based polling firm that executed the poll.

In Pennsylvania, Clinton leads Trump with 46 percent to his 43 percent, and in North Carolina the former first lady leads Trump 44 percent to the New York City developer’s 43 percent, he said.

Before unlikely voters were filtered out of the sample population, the results were similar with candidates tied in Minnesota and Clinton up one point in North Carolina and up two points in Pennsylvania.

Democratic pollster Patrick Caddell told Breitbart News: “Trump is closing everywhere and states that have not been in play are coming into play, like Minnesota.”
