Mark Halperin's reported monologue takes on the biggest and most under-covered 2028 presidential campaign question: can Bernie Sanders overcome questions about his age and win the nomination? What would he need to do to silence the doubters, even as his movement continues to dominate the Democratic Party. Then, Mark is joined by Megyn Kelly to discuss the rise of socialism in America, anti-Israel sentiment, and the areas of growing frustration within the Republican Party. Megyn also weighs in on JD Vance vs. Marco Rubio, and why the VP has lost ground in some quarters.
