Yet there is a possible workaround in Massachusetts that could shorten the window for a Republican appointment and a special election if Warren becomes president.
Under state law, an outgoing senator could file a letter of resignation, triggering the 145- to 160-day period to hold a special election — but not make the resignation effective until a later date.
So Warren could file that letter the day after Election Day — or even earlier during the general-election campaign — to expedite the date of the special election and minimize the time of any Republican replacement.
