Why Is CVH in a Philadelphia Congressional Primary?
By Barry O’Connell
Maryland Democrats may want to pay attention to a congressional primary taking place across the state line in Philadelphia.
At first glance, it looks like a local Pennsylvania race. It is not.
The Democratic primary for Pennsylvania’s 3rd Congressional District has become a proxy fight over the future of the Democratic Party. And Maryland’s senior senator, Chris Van Hollen, known to many Maryland political insiders as CVH, has chosen a side.
He is backing State Representative Chris Rabb, the most openly progressive candidate in the race.
That matters.
The Philadelphia seat is being vacated by longtime Congressman Dwight Evans. The district is one of the most Democratic seats in the country, which means the May 19 Democratic primary is almost certainly the real election. The main Democratic candidates include State Senator Sharif Street, State Representative Chris Rabb, Dr. Ala Stanford, and Shaun Griffith. Street is the son of former Philadelphia Mayor John F. Street and a former chair of the Pennsylvania Democratic Party. Rabb is a movement progressive with support from the organized left. ([6abc Philadelphia][1])
This is where the Maryland angle comes in.
CVH is not from Philadelphia. He does not represent Pennsylvania. He does not have an obvious constituent-service reason to be involved in this primary. Yet Rabb’s campaign lists Van Hollen as one of its national elected endorsers, alongside Jamie Raskin, Alexandria Ocasio-Cortez, Ilhan Omar, Pramila Jayapal, Ro Khanna, Rashida Tlaib and Maxwell Frost. ([Jewish Insider][2])
That is not a random list. That is a faction.
This is the left wing of the Democratic Party trying to add another vote to Congress.
Sharif Street, by contrast, has the backing of much of the Philadelphia political establishment. Philadelphia Mayor Cherelle Parker endorsed Street, saying he would be a reliable partner in Congress for securing federal support for the city. Street also has support from the city Democratic committee and major labor organizations. ([Axios][3])
So this is not merely Rabb versus Street.
It is movement left versus regular Democratic organization politics.
It is national progressive politics versus local Philadelphia machine politics.
It is also, unmistakably, a fight over Israel, Gaza and the future of Democratic foreign policy.
Jewish Insider described Rabb as an Israel critic who has drawn support from progressive heavyweights, including Van Hollen, Raskin, Omar, Khanna and Jayapal. The same report contrasted Rabb with Street, who is described as a pro-Israel Muslim Democrat who supports a two-state solution and has worked to promote Jewish-Muslim ties. ([Jewish Insider][2])
That does not mean CVH endorsed Rabb only because of the Middle East. But anyone who follows Van Hollen’s recent political positioning knows that he has become one of the Senate’s more prominent Democratic critics of the Netanyahu government. His endorsement of Rabb fits that broader pattern.
This is where Maryland readers should pause.
Van Hollen has always been a careful politician. He is not usually impulsive. He does not typically throw his name into races without some calculation. So when he steps into a Philadelphia congressional primary, he is sending a signal.
The signal is that CVH is increasingly comfortable aligning himself with the national progressive wing of the Democratic Party, even when doing so means intervening in another state’s local political fight.
That raises a legitimate Maryland question.
Is Van Hollen still mostly acting as Maryland’s senior senator, or is he now also positioning himself as part of a national progressive bloc that wants to reshape the Democratic caucus?
This is not a small point. Maryland already has Jamie Raskin, who has become one of the most visible progressive constitutional voices in the country. Now Van Hollen is appearing in the same endorsement lane as Raskin, AOC, Omar, Tlaib, Jayapal and the Congressional Progressive Caucus orbit.
That may excite some Maryland Democrats. It may worry others.
For progressives, Rabb represents the future. He is a sharp, ideological, movement-oriented candidate who speaks the language of the activist left. For traditional Democrats, Street represents something very different: experience, institutional relationships, local government, labor support, and the kind of coalition politics that has long powered big-city Democratic machines.
One can argue that either model has value.
But Maryland readers should understand what CVH is doing.
He is not merely endorsing a friend. He is not making a courtesy gesture. He is taking sides in a factional fight.
And that factional fight is not confined to Philadelphia.
It is happening in Maryland. It is happening in New York. It is happening in Pennsylvania. It is happening inside the Democratic caucus in Washington.
The question is whether Democrats want more candidates who come out of the activist-left pipeline, or more candidates who come out of the local party, labor, and governing institutions that have traditionally produced Democratic officeholders.
Van Hollen has now given his answer in Philadelphia.
Maryland Democrats should notice.
