WASHINGTON _ As the Democratic presidential primary campaign unfolds, a network of Pennsylvania donors and political leaders are waiting on one man: Joe Biden.
A cadre of old-guard fundraisers and insiders view the former vice president as a familiar and safe choice against President Donald Trump, especially given his deep ties to Pennsylvania, likely to be a crucial swing state in 2020. Many have said they would support Biden if he announces a candidacy in the coming days, as party insiders increasingly expect.
The anticipation has intensified as Biden prepares to speak Tuesday to the International Association of Firefighters convention in Washington. It's the kind of event that Biden supporters say will showcase the blue-collar appeal they believe makes him Democrats' best bet to unify the party and win back states such as Pennsylvania, Michigan and Wisconsin, where many white, working-class voters turned to Trump in 2016, helping tip the election.
"If I were to guess, I'd guess he's going to run," said Sen. Bob Casey, D-Pa., who on Wednesday said he had spoken to Biden, a fellow Scranton native, within the previous 10 days. (Casey has not said who he plans to support).
Former U.S. Rep. Bob Brady, chairman of the Philadelphia Democratic Party, said Biden "keeps telling me to keep my powder dry," and that he is ready to back his longtime friend.
And Sen. Chris Coons, D-Del., was "optimistic" that Biden will join the contest. Echoing others, Coons praised Biden's experience in international affairs and potential appeal to a wide variety of voters.
"His ability to repair the damage that's been done to our place in the world is unmatched," Coons said. On many issues "he gets the experience of the middle class in the United States better than any candidate in the field."
Biden's route to the Democratic nomination became clearer this week when two potential ideological and stylistic rivals chose not to run. Former New York Mayor Michael Bloomberg, who would have run as a centrist, and Sen. Sherrod Brown, D- Ohio, who has a Midwestern working-class appeal, announced they wouldn't run.
Their decisions could leave Biden as one of the few Democrats running on a moderate message, with Sen. Amy Klobuchar of Minnesota and former Colorado Gov. John Hickenlooper.
Although he represented Delaware, Pennsylvania Democrats have long treated Biden as one of their own. Since leaving the vice presidency, he has established the Biden Center for Diplomacy & Global Engagement at the University of Pennsylvania and is said to be considering Philadelphia or Wilmington, Del., as a base of operations in a presidential run.
Pennsylvania Democrats still regularly seek his support, viewing Biden as an ally who can connect with voters in areas where the party has been in retreat. Last year Biden rallied with Casey during the senator's re-election bid, campaigned with U.S. Rep. Conor Lamb as he ran in a Trump-friendly district in Western Pennsylvania, and marched in the Pittsburgh Labor Day parade. He has decades-long ties to many Pennsylvania political players.
"In the conventional donor marketplace, Joe has 80 to 90 percent of the Philadelphia givers and raisers waiting for him to run," said former Pennsylvania Gov. Ed Rendell, though he noted that significant fundraising comes from small donations online.
Rendell said he is "inclined" to support Biden if he runs, and called him as the kind of candidate who can win both fervent Democrats and moderate voters.
"Joe Biden is a 10 on the experience rating," Rendell said. "Everyone else is a five or lower."
Some major Pennsylvania donors, however, are still waiting to see how the field takes shape, and few Democratic candidates have made sustained attempts to win the support of the state's political elite so far.
Longtime Biden allies and fundraisers Tom Leonard and Stephen Cozen, partners at Center City law firms, said they will back him if he runs. Each said Biden is the best option against Trump, especially because other Democratic contenders have supported liberal proposals that they fear could play poorly in swing states.
"If Trump can run against socialism, he has a decent shot to be re-elected," Leonard said.
Another Philadelphia fundraiser, lawyer Kenneth Jarin, said he is "very inclined" to support Biden, though he also likes several current or former Democratic governors in the race or considering campaigns.
"The ultimate priority here is to win, and I think at least at the moment he appears to be the strongest candidate, if he runs, in terms of ability to beat Trump," Jarin said. "But I think we're a long way from really knowing the answer. I think this has to play out before anyone can really know."
While Biden has led in early polling, there are many months to go and he would confront a crowded, diverse Democratic field. Biden has failed in two previous presidential campaigns, and at 76 faces questions about his appeal and stamina for the job. Many of the insiders lining up for Biden are older white men with pro-business views, while much of the Democratic debate is being driven by younger and minority voters eager for new voices and bold ideas.
Biden's longevity has built him substantial Democratic support, including with blacks, but some of his record looks out of step with the today's party. In recent months he has tried to ease concerns about how he led the Senate Judiciary Committee when it questioned Anita Hill about her sexual harassment accusations against Clarence Thomas at his Supreme Court confirmation hearing, and over his support of a 1994 crime bill blamed for disproportionately punishing minorities. Some liberals have bristled at his chummy approach to Republicans, including Vice President Mike Pence.
On Thursday, The Washington Post resurrected comments from 1975 in which Biden spoke out against school busing to promote integration.
"He has a lot more history and connection to the state, but I think like anything he's going to have to compete to win," said U.S. Rep. Dwight Evans, D-Pa. "This is not going to be decided by insiders. It's going to be decided by people."
Pennsylvanians, however, may have little direct say, since the state holds its Democratic primary in April 2020, late in the nominating contest.
But backing from Pennsylvania's donors could bolster Biden as he competes elsewhere and support his supporters' argument that he has the best odds in the places that matter most in the general election.
