As the tin says, what if OTL Vice President George M. Dallas had been President. There was a short what if thread about James K. Polk dying in the middle of the Mexican-American War. This could be a viable POD instead of him just running to succeed Polk after he finishes his term.
What would his presidency look like if he had succeeded Polk in the middle of his term? What if instead he had just been the Democratic nominee after Polk's presidency? How do you think he would be remembered in either case?
