But two recent Quinnipiac University polls show her unfavorability rising in swing states. She now trails Jeb Bush by one point, after leading him by 10 in May, and Joe Biden leads Jeb by one point.

Many Democrats fret that she seems more impatient than hungry, more cautious than charismatic. They are increasingly concerned that, aside from the very liberal Bernie Sanders, who could be approaching his ceiling in the early states, there is no backup if something blows up — no Jimmy Garoppolo to step in while Brady is suspended for four games.

Potent friends of America’s lord of latte, Howard Schultz, have been pressing him to join the Democratic primary, thinking the time is right for someone who’s not a political lifer. For the passionate 62-year-old — watching the circus from Seattle — it may be a tempting proposition.

After coming up from the housing projects in Brooklyn, Schultz reimagined Starbucks and then revived it. He has strong opinions, and even position papers, about what he calls the fraying American dream. While he was promoting his book on veterans last year, he honed a message about making government work again and finding “authentic, truthful leadership.”

Joe Biden is also talking to friends, family and donors about jumping in. The 72-year-old vice president has been having meetings at his Washington residence to explore the idea of taking on Hillary in Iowa and New Hampshire.

He gets along with Hillary and has always been respectful of the Democratic Party’s desire to make more history by putting the first woman in the Oval Office.

But going through the crucible of the loss of his oldest son, Beau, to brain cancer made the vice president consider the quest again.
