The bait has been put in the bear trap. The promise to legalize drugs is causing a lot of Pennsylvanians to make a very bad decision for Fetterman.
Fetterman can’t, on his own, legalize drugs. He’d need a majority in the Senate and House to change the law afaik.
Someone with the long term strategy of legalizing recreational drugs might want him in there but he is nowhere near with a majority and, I doubt, every would be.
