Vice President Kamala Harris’s recent surge in the polls may not be enough to defeat former President Donald Trump in November, according to Democratic strategist James Carville.

Carville, while speaking on MSNBC’s “The Beat” insisted that Harris is nowhere close to beating Trump in November. Carville cautioned democrats who are getting carried away by the recent excitement and enthusiasm surrounding the vice president.

“People would be wise to listen to Dave Wasserman, who you just had on, who is a very wise man, who said if we need to win this thing, we have to win by two. Some people say maybe we even need to win by three, and we are not close to being there yet. We need to keep our heads down. We need to have a good convention in Chicago. We need to go out campaigning and we need to launch attacks. We’ve got to go here. We’ve got to hit them hard. I think that the early signs are encouraging. I’m not going to be. I don’t want to be a downer here, but we have to be realistic. And you and I are a little older. We know a lot about what politics is, and we know someone about what motivates different people in this country.”

Carville’s warning comes after a recent Harvard-Harris poll showed the former President leading Harris by three points. The poll, conducted between July 26 and 28, surveyed 2,196 registered voters across America.

When asked who they would vote for if the presidential election were held today, 48% of respondents chose the former President, with 45% opting for Harris. Seven percent of voters surveyed could not decide between both parties.

The poll also found that 48% of voters had a “very favorable” or “favorable” view of Donald Trump, while 47% viewed the vice president similarly. Around 48% of voters expressed a “very unfavorable” or “unfavorable” view of Trump, while 47% expressed the same for Harris.
