Sen. John Fetterman (PA) is having doubts that the Democratic Party is “big” enough to welcome his values despite Senate Minority Leader Chuck Schumer (NY) pressing the nonconformist Democrat to remain in the party.

Fetterman has been dodging speculation that he may cross the aisle, but the idea seemed far-fetched until fellow Democrats started backing opposition to Israel, something Fetterman has said is nonnegotiable.
