Democratic Pennsylvania Senator John Fetterman has lost his unique leverage in Washington now that his party has pulled off a blue wave in the midterm elections.

The Democratic Party was handed control of the House and the Senate on Tuesday, dramatically reshaping Congress for the country.

In Pennsylvania, Fetterman has wielded the power of being the deciding vote in what was a narrowly divided Senate, as a Democrat willing to break with his party. But Democratic Senate gains across the country on Tuesday have pushed their seats from a minority of 47 to a majority of at least 54, after flipping at least seven seats, as of early Wednesday morning.

This means Fetterman, who has long faced criticism from wings of his party for obstructing the Democratic agenda by voting with Republicans, will now have less power to force his party to listen to the views he represents.
