And fetterman isn't even the worst/most far right dem just currently the most visible

Fetterman still votes with Democrats about 75-80% of the time. He is not ideal, but he is far better than any Republican.

Elected representatives are intended to vote the way their constituents want them to. Foreign military intervention and border control are very popular in Pennsylvania and those are the two major categories where Fetterman diverges from the Democrats.

On top of all that, the parties don't ever kick people out for how they vote. They only kick people out for misconduct.

Fetterman, a gift brought to you by Bernie
