Pollsters got it “wrong” in the final days of the 2024 presidential campaign by overlooking a “massive shift” in voter registration since the last election – which could tip the scales Tuesday in favor of former President Donald Trump, a veteran Republican, he says Strategist.

Alex Castellanos, who worked on campaigns for Jeb Bush and Mitt Romney, told Fox News' “Special Report” that the polls – which show a razor-thin gap between Trump and Vice President Kamala Harris – discount a “wave out there.” let Republican enthusiasm.”

“What I think they're missing is a massive shift in voter registration that's behind all of this. Thirty-one states have voter registration by party. “Thirty of them have seen a move toward Republicans in the last four years,” the longtime strategist said late Sunday.

“I think there's a wave, I won't call it a wave, but I think there's a wave of Republican enthusiasm and registration out there. What should I do if I register to vote Republican, whether I’m switching or new?”

Castellanos suggested that the lack of statistical variation in polls released in the final phase before Election Day was due to a failure to detect this increase.

“I think the pollsters are getting this wrong. We all miss something because they keep giving us the same survey. There’s not even a statistical difference,” Castellanos said.

“It’s like they’re telling us we’re watching a basketball game where every play is a jump ball.”

A handful of new polls over the weekend showed six of the seven battleground states close enough to be within the margin of error – with the only clear frontrunner being Arizona, where Trump has a four-point lead.

Trump held a 49% to 45% lead in the Grand Canyon State, while two others show him tied with Harris – 48% in Pennsylvania and 47% in Michigan, respectively, according to the latest New York Times swing state poll and Siena College.

Harris won narrow leads within the margin of error among likely voters in Nevada (49% to 46%), North Carolina (48% to 46%), Wisconsin (49% to 47%) and Georgia (48% to 47%). .

Meanwhile, other prominent analysts – including poll data guru Nate Silver – have also started asking questions about polls in recent days, claiming that some pollsters are confusing the results with decisions aimed at showing a close race. in order not to stand out as an outlier.
