CNN panel breaks down new polling ahead of the DNC kick off

David Gergen : Joe Biden is going to talk about Kamala Harris in the future, but hopefully he'll talk about her.

Gergen says Biden should acknowledge the success of his presidency, but not just talk about the future but why he picked her to be his number two .

He says Harris 's numbers that look very different from Biden 's; she's taking away from RFK Junior . She's bringing and some more of those undecideds. The question will be, with this convention, does she deliver a message that can secure those voters to her. It's not a disadvantage because she hasn't been a good vice president. This is just the nature of the role..

Republican Congressman Adam Kinzinger is going to speak and endorse Kamala Harris on Thursday night .

Suduna Suduna says it's going to be interesting to see how that plays out.

Donald Trump has had a great line at the press conference of Bedminster . He said, you know she's ready on day one to take on these problems. Her day one was 3 1/2 years ago . Why not take care of it right now? But she benefits greatly.

The double haters, though, are going more towards Kamala Harris than they are Donald Trump . And that's a good thing for Thanks one and all for being here..
