Some interesting polling......

 IF you trust YouGov. 

A recent YouGov survey asked Democrats, Republicans, and Independents who lean towards either party about potential 2028 presidential candidates.

Gavin Newsom and Kamala Harris are the politicians among a list of 12 in the poll whom Democrats and Democratic-leaning Independents are by far most likely to say they'd consider voting for in a 2028 Democratic presidential primary: 55% say they'd consider Newsom, and 54% Harris.

(If the Dems go with Harris they will be committing political suicide, just my opinion)

Newsom's standing has risen significantly since similar questions were asked on the Economist/YouGov Poll in April. The share of Democrats and Democratic-leaning Independents who say they would consider voting for him as the Democratic nominee in 2028 has risen 24 percentage points, to 55% from 31%. The share who say Newsom is their ideal candidate has increased 16 points, to 23% from 7%.

Democrats and Democratic-leaning Independents are most likely to say they'd be disappointed to have Harris (19%), Sanders (18%), or Booker (17%) as the 2028 nominee. The shares saying they'd be disappointed by Booker, Buttigieg, Whitmer, or Kelly becoming the Democratic nominee have increased since April, while the share who'd be disappointed by Newsom as nominee has declined.

(Now, there is a shocker. Why would Buttigieg and Booker's numbers be declining? I happen to really like both as possible VP candidates)

Among Republicans and Republican-leaning Independents, by far the largest share say JD Vance (65%) is someone they would consider voting for in the 2028 Republican presidential primary, from a list of 11 options in the poll that did not include President Trump; respondents could select all whom they would consider.

Vance is followed by Ron DeSantis (40%), Donald Trump, Jr. (37%), Marco Rubio (33%), and Ted Cruz (29%). 

(Don Trump Jr? I hope they run him, it would be as bad for the Republicans as running Harris would be for the Democrats.)

Finally:

Nearly half (46%) of Americans expect that Trump will attempt to serve a third term as president, while 37% think he will not. Democrats are more than twice as likely as Republicans to think he will attempt to do so (67% vs. 27%).

Only 13% of Americans think that Trump should attempt to serve a third term; 78% think he should not. Among Republicans, 30% think he should do so, while 58% say he should not.
