What Democratic nominee would create this electoral map

[President Johnson]

I doubt this map is possible for 2024 under any realistic candidate or scenario, though in 2028 after another disastrous term of Trump and a weak Republican candidate versus a strong Democrat like Whitmer, Moore, Beshear, Shapiro or Warnock, it's very much within the range of possibilities.

Ironically, it's actually what I have as the 2024 election result in my novel, in which the incumbent president (the main character of the story) wins a full term in office after succeeding his predecessor in August 2021 following a health-related resignation. But unlike any current politician, he's a charismatic, good looking 49-year old mainstream Democrat with a background as successful businessman while his opponent is (somewhat an analogy to Trump) the former Republican president (a woman) that was already voted out in 2020. In an October surprise, the divorced president admits his love for a former 33-year old staffer who's introduced as First Lady and wins the hearts of the nation. As black woman, she helps turn out the African American vote. He's also fluent in Spanish, what gets him an additional boost while the female vice president appeals to many suburban voters, especially white women. So unique circumstances that won't happen next year.
