With Biden out, Josh Shapiro emerges as possible VP pick

With President Biden ending his re-election bid , there's growing chatter that Pennsylvania Gov. Josh Shapiro could be a potential running mate for Vice President Kamala Harris .

Why it matters: Shapiro, who's positioned himself as a moderate Democrat, has many advantages for a national ticket, including representing a pivotal swing state that former President Trump 's campaign has indicated will be central to their campaign strategy.

• The former state lawmaker and attorney general has decades of political experience, and some swing voters view Shapiro as Democrats' next rising star.

The big picture: Shapiro is among several Democratic governors getting attention for the VP spot, as well as North Carolina Gov. Roy Cooper, Michigan Gov. Gretchen Whitmer, Illinois Gov. J.B. Pritzker and Kentucky Gov. Andy Beshear.

• Some Democratic officials and operatives have even floated Shapiro's name as a presidential contender should delegates and party members decide Harris isn't the strongest opponent to take on Trump.
• As of Sunday, no major Democratic lawmaker had indicated their intention of challenging Harris for the party's nomination.

Reality check: Democrats are unlikely to leapfrog Harris in favor of another candidate for several reasons — including the millions of dollars held in the Biden-Harris war chest that could easily be given to her, but not to any other potential candidate.

Catch up quick: President Biden announced in a letter posted on his X account Sunday that he's stepping aside as the presumptive Democratic nominee for the 2024 presidential contest and endorsing Harris.

• Biden, who has been in Rehoboth, Delaware, since last week recovering from COVID-19, faced intense pressure to withdraw from the race following his shaky debate performance on June 27 against Trump.
• Harris is emerging as the leading contender weeks before the Democratic National Convention on Aug. 19, but some advisers worry the VP's record may not outweigh her years-long battle with public image and low favorability ratings, Axios' Avery Lotz reports .

What they're saying: "I will do everything I can to help elect Kamala Harris as the 47th President of the United States," Shapiro said in a post on X Sunday.

• "I've known Kamala Harris for nearly two decades — we've both been prosecutors, we've both stood up for the rule of law, we've both fought for the people and delivered results," Shapiro wrote in a statement. "She has served this country honorably as Vice President and she is ready to be President."

When speculation was swirling before Biden stepped aside, Shapiro said he was committed to staying put as Pennsylvania governor.

• His spokesperson Manuel Bonder told Axios earlier this month that any scenario of the governor replacing Biden or becoming Harris' VP pick was "baseless speculation" and a "distraction" that doesn't help Democrats "defeat Donald Trump at the ballot box."

Zoom in: Shapiro, a first-term governor, has navigated the state's divided government and could appeal to constituents in Philadelphia's purple suburbs.

• Shapiro has been outspoken about the ongoing war in Gaza and was credited for his leadership in getting I-95 reopened in less than two weeks after a deadly collapse .

Between the lines: St. Joseph's professor emeritus and political commentator Randall Miller tells Axios that Shapiro is better off remaining at the helm in Pennsylvania and positioning himself to run in the next cycle.

• He could decimate future political prospects by joining a potentially "sinking ship."
• "He's very independent, very shrewd," Miller said. "He has a controlled, directed ambition. He doesn't need to do it."

What's next: Harris will not automatically pick up Biden's delegates, meaning her road ahead has to focus on accumulating a majority at the DNC.
