PHILADELPHIA The hulking, big-hearted mayor of Braddock, Pennsylvania, is not especially welcome in Washington, D.C.

Its not that the 46-year-old, 6-foot-8 John Fetterman cant get a meeting with the power brokers in the nations capital. But the one he got last year with the Democratic Senatorial Campaign Committee showed that the antipathy is at least somewhat mutual.

We did talk to the DSCC in D.C., Fetterman recalled Friday, sitting outside a donut shop and cafe before taping the final debate of a Democratic Senate primary that features front-running former Rep. Joe Sestak and Katie McGinty, the former chief of staff to Gov. Tom Wolf.

We talked to them actually for four or five hours, and they were like, Hey, you guys, you know, good with us, and Were staying out of it.

But as of last week, the DSCC had spent about $1.5 million on advertising for McGinty.

They reneged on that promise, clearly, in a big, big way, Fetterman said. Thats the only conversation that weve had in Washington with the elites or the establishment.

Fetterman is not especially surprised. He's the sort of outsider whose ideas about inequality and belief in the need for fundamental change have long alarmed cautious, triangulation-prone party leaders who now worry that Bernie Sanders (I-Vt.) is making overly bold promises that he can't possibly deliver. But Fetterman is also exactly the sort of candidate who, if he can win, would give Sanders a better chance of passing things like a $15 minimum wage, universal health care and free public college. And right now, not only are Democratic Party leaders not helping, they're standing in the way.
