Kerry and Edwards need to resign the Senate

[True Federalist (진정한 연방 주의자)]

If I understand the law correctly, don't they have to resign from the Senate once they accept the nomination at the convention?

I tihnk they have to resign by Jan. 6.

Jan. 6 is the day the Congress counts the electoral college votes by law, so since the result won't be official until then at the earliest that would be sensible, but I'd be surprised if the law requires resigning any other office at a specific point in time befor ebeing inaugurated.
