CNN data reporter says Kamala Harris is in a "danger zone" in swing states, and national polls are irrelevant.

CNN data reporter Harry Enten warned that Vice President Kamala Harris' current poll numbers in key battleground states put her in the "danger zone" for winning the electoral college.

"In the seven key battleground states, the race between Harris and Trump is significantly tighter than the national average margin."

Most national polls, Enten noted, show Harris leading former President Trump.

According to Enten, if Harris wins the popular vote by two to three points, her chances of winning the Electoral College are only 53%. To have a clear, clear, clear chance of winning the majority, Harris needs to win by about three to four points. If she wins by less than two points, her chances of winning are only 23%. Currently, Harris is in the danger zone where about half the time, given the national popular vote margin, she would win.

Currently, Harris has a 70% chance of winning the popular vote but only a 50% chance of winning the electoral college, according to Enten.

As of today, there is approximately a 20% chance that Kamala Harris will win the popular vote but lose in the Electoral College.

According to Enten, we could be heading towards a split similar to those seen in 2016 and 2000, where Kamala Harris wins the popular vote but loses in the Electoral College. Currently, we are in a "weird middle zone" where the outcome is uncertain based on the popular vote, which is why national polls showing Kamala Harris ahead do not matter as much at this point.

Despite Harris' polling gains, Trump still had a good chance of winning in August, as Enten stated, because Trump has historically been underestimated in polling.

If you're a Kamala Harris supporter and you're planning to celebrate her victory by opening a champagne bottle, don't do it. Donald Trump is still very much in the race, and if there's a polling shift like we've seen in the past, he could actually win. While it's uncertain whether this will happen, Enten believes that Trump is still a formidable contender based on his current position and compared to where he was in previous years.

On Sunday, a poll showed that Trump's lead in Iowa, which he won by 9 points in both 2016 and 2020, had narrowed.

The Des Moines Register/Mediacom Iowa Poll released Sunday shows that Harris has reduced Trump's lead in Iowa by four points, with Trump leading Harris 47% to 43%.
