Politician smeared during election? Shock horror, it happens during every election.

Leader of the party can't unite their own party so there is a plan to oust them? That's politics.

Jeremy couldn't particularly unite the party, didn't take the center ground, and while I don't think he was a true antisemite there were enough mis-steps there that it meant that the claim could stick (along with the IRA sympathizer claims).
