Secretary of Transportation Pete Buttigieg and Michigan Gov. Gretchen Whitmer have the strongest approval rating among Democrats of the potential running mates for Vice President Harris if she, as expected, becomes the party’s 2024 presidential nominee, according to a YouGov poll released Monday.

In the poll, 59 percent of Democrats say they strongly or somewhat approve of Buttigieg, compared to only 14 percent who say they disapprove. Whitmer — who has said she is not being vetted as a VP contender — received 50 percent approval, compared to only 13 percent who say they disapprove.

Polling suggests that Buttigieg may be the favorite among voters. New polling released by ABC News/Ipsos on Sunday showed Buttigieg with a higher favorability rating than other Democrats reported to be on Harris' shortlist.

Buttigieg was viewed favorably by 29 percent of respondents, with Kelly coming in second at 22 percent. Following them, Governor Gavin Newsom of California was at 21 percent and Whitmer was at 20 percent. Shapiro came in at 17 percent.

The survey included 1,200 respondents and was carried out from July 26 to 27. It has a margin of error of 3 percentage points.

A new Quinnipiac University poll finds that 70% of voters (including 86% of Democrats and independents who lean Democratic) say they are open to electing a gay president.
