It somehow seems par for the course.

Philadelphia, which is getting ready to host the Democratic National Convention July 25-28, saw its most prominent Democratic politician convicted this week on federal racketeering and bribery charges.

U.S. Rep. Chaka Fattah, D-2nd District, one of Pennsylvania’s longest-serving members of Congress, was found guilty on all 22 charges he faced, including money laundering and fraud.

Fattah’s crimes included the theft of funds from an education nonprofit to repay an illegal $1 million campaign loan, according to prosecutors. He also was found guilty of misdirecting federal grant money to a fake nonprofit to pay one of his political strategists, and siphoning campaign money to pay his son’s college debts.

Fattah, 59, said he’ll resign on Oct. 3.

Philadelphia is no stranger to corrupt politicians. Congressmen Mike “Ozzie” Myers and Ray Lederer, both Democrats were convicted in the FBI Abscam sting in 1980 and served time in prison. Lederer was even re-elected while awaiting trial.

More recently, state Sen. Vincent J. Fumo, the top-ranking Philadelphia Democrat in the Legislature, was found guilty of fraud. He was released from federal prison in 2013.

Leanna Washington, a Democratic state senator from Philadelphia, pleaded guilty to felony conflict of interest in 2014. Washington used her staff to plan birthday party campaign fund-raisers from 2005 to 2013, using up to $100,000 in taxpayer money for political gain, prosecutors alleged.

And then there were the four prominent Philadelphia Democrats in the state House, implicated in a sting operation that was quietly dismissed by Attorney General Kathleen Kane but picked up by Philadelphia District Attorney Seth Williams. Three of the state representatives pleaded guilty to accepting bribes; the fourth pleaded no-contest.

There’s the ongoing saga of Kane herself, under indictment and suspension of her law license, accused of leaking grand jury information and then lying about it. Four years ago, Kane was a rising star in the Keystone Democratic delegation and a pillar of support for Clinton. Now she is neither.

It should make for an awkward welcome next month for presumptive presidential nominee Hillary Clinton and the Democratic National Convention, and Fattah is not the only Pennsylvania Democratic dealing with such distractions.

Another party stalwart, former Gov. Ed Rendell, might be muted by the fact that some of Fattah’s inner circle were also convicted included Herbert Vederman, a deputy mayor under Rendell.

Gov. Tom Wolf might still be wrangling with the Legislature over a 2016-17 state budget — they blew the previous July 1 budget deadline by nine months. The negotiations reportedly are going a little more smoothly this year, but not many details have been released and the deadline is only one week away.

That leaves U.S. Senate candidate Katie McGinty, whose official campaign website tells us more about the job performance of her opponent, Republican Pat Toomey, than about her own qualifications. McGinty has abandoned the claim that she was the first of her 10 siblings to attend college when it was disclosed her older brother was first to attend.

It’s likely that McGinty, Rendell and Wolf will be front and center when Philly rolls out the DNC red carpet. What’s less certain is how they’ll tout their accomplishments or vision for Pennsylvania.

It would be a good time for new leadership to emerge from the state Democratic Party. Maybe Seth Williams, the Philly DA.

Pennsylvania — Philadelphia in particular — could benefit from a fresh infusion of Democratic Party leadership when the party convenes a month from now.
