NEW YORK — The senior political editor at NBC News, Mark Murray, now expects the presidential election to be close in Wisconsin. The late entry of Democrat Kamala Harris, replacing incumbent Joe Biden, has tightened the campaign season and rattled the GOP’s Donald Trump. “So far, the short campaign seems to be benefitting Harris and the Democrats,” Murray said. Further, he said, Democrats can expect momentum from their just-completed national convention in Chicago. Even so, Murray added, the Harris course in Wisconsin won’t be a cake walk. “How Harris is able to withstand when the going starts getting tough, to me, is one of the bigger developments we will have seen. History doesn’t provide clear indicators, he said: “Wisconsin was the tipping point state in 2016, it was the tipping point state in 2020, and it very well could play that role again in 2024, being the decisive state that pushes either the Democratic nominee or the Republican nominee across those 270 Electoral College vote.”
