New polls show Harris ahead of Trump in three major states.
After the U.S. election system based on male voters, the three populous states in the Midwest are crucial for both parties to win. The so-called swing states, which cannot be clearly assigned to either political camp, often decide U.S. presidential elections.
This reverses the poll results in the three states where Trump has been neck and neck with or slightly ahead of incumbent President Joe Biden for nearly a year, who withdrew his candidacy last month and instead supported his vice president, Harris.
Much can change before the presidential election on November 5. According to the new poll, voters in central issues like the economy and immigration still prefer Trump, while Harris leads Trump by 24 percentage points on the question of who to trust on abortion.
Nevertheless, Democrats draw encouragement from the enthusiasm generated by Harris' candidacy. Many express relief since the 81-year-old Biden dropped out of the race for the White House.
Harris' decision to choose Minnesota Governor Tim Walz as her running mate for vice president also seems to have further energized U.S. Democrats. The enthusiasm for the new duo of Harris and Walz has slowed down the increasing support for Trump, which he enjoyed after the attack on him on July 13 and the Republican convention.
In the state of Pennsylvania, Harris' popularity among registered voters surged by ten percentage points in just one month, according to a poll by "New York Times" and Siena College. Voters said Harris is smarter than Trump and more suitable to govern the country.
Among Democrats, satisfaction with their candidates in the three states has risen by 27 percentage points since May.
However, observers warn Democrats not to get too optimistic, as Trump still leads in national polls.
The polls by "New York Times" and Siena College were conducted between August 5 and 9, with at least 600 voters surveyed in each of the three states.
In the recent polls, incumbent President Joe Biden's performance has improved in key states, despite withdrawing his candidacy and supporting his vice president, Harris. Trump remains ahead in national polls, but Harris' popularity has surged in Pennsylvania, with voters favoring her as a smarter and more suitable leader.
