I will say, these are very weak numbers for Harris's 2028 outlook. She's "leading" with 25% as the sitting VP against a field of also rans and ocotgenarians. She'd be very weak as the nominee going in a general election against any Republican, and I think these numbers show that most Democrat primary voters know she is weak. 2028 will provide better options than her, it's more a question of who? Warnock (if Georgia elects a D Governor in 2026)? A re-elected Shapiro? Mark Kelly? Whitmer? Wes Moore?
But that field of also rans and octogenerians is also the most likely one, so she is the favourite currently.
Or do you think Newsom at half her numbers, or Whitmer at 1/5th of her numbers are actually going to do far better than what the poll suggests.
