  • UnitedHealth's stock has "caught fire" due in part to Warren appearing to "back away" from her "Medicare for All" proposal, according to Jim Cramer.
  • The stock has also rallied because Warren has faltered in some political polls, Cramer says.

UnitedHealth's stock has "caught fire" due in part to Sen. Elizabeth Warren appearing to "back away" from her "Medicare for All" proposal, CNBC's Jim Cramer said Monday.

Shares of the managed-care company got hammered in September when Warren became the new frontrunner in the crowded 2020 Democratic presidential race. Warren's platform has called for the elimination of private health insurance, like UnitedHealth, and replacing it with a universal Medicare plan for all Americans.
