CNN (Cable News Network) released key poll results for the critical 'Blue Wall' three states on Wednesday (October 30). Democratic presidential candidate Harris is leading in two states, while tied with Republican opponent Trump in one state.

The so-called 'Blue Wall' states refer to Michigan, Wisconsin, and Pennsylvania, which are three key battleground states.

As the countdown to the U.S. presidential election begins, according to CNN's latest poll, among likely voters in Michigan, Harris has a support rate of 48%, ahead of Trump's 43%; in Wisconsin, Harris leads Trump with 51% to 45%.

However, in the critical state of Pennsylvania, both candidates have equal support at 48%. Pennsylvania has 19 electoral votes and is a battleground that has been fiercely contested in past U.S. presidential elections.

Trump swept the three 'Blue Wall' states in 2016, but four years later, President Biden reclaimed those states.
