New York Times: “As much as the president wants to turn to his looming fight against a Republican — he has signaled he is itching for a rematch with Mr. Trump — his Democratic allies warn he has significant work to do with voters in his own party. He still has to find ways to promote his accomplishments, assuage voters wary of his age and dismiss the Democratic challengers he does have without any drama.”
“Those upstart rivals include Robert F. Kennedy Jr., the anti-vaccine activist with a celebrated Democratic lineage who has emerged with unexpected strength in early polls even as he spreads conspiracy theories and consorts with right-wing figures and billionaire donors. Mr. Kennedy’s support from Democrats, as high as 20 percent in some surveys, serves as a bracing reminder of left-leaning voters’ healthy appetite for a Biden alternative, and as a glaring symbol of the president’s weaknesses.”
