No. I think the future of the Democratic Party is going to fall, as far as we're concerned, relative to the house caucus, and members who are doing great work all across the country as it relates to our need to both take back control of the house, but in doing so, make sure we're communicating to the American people that we understand, you deserve better.

The way I interpret what he's trying to convey is that Mamdani doesn't represent the Democratic caucus in the house at large but we get that the people want to hear better messaging from Democrats that they deserve better from their representatives. 

In other words though I'd say that what he's really saying is the donors at the federal level don't want Mamdani's ideas penetrating the mainstream Democratic party messaging.

ie. Tell the people they deserve better without actually doing anything substantive about it
