The prez would choose his replacement pending senate advise and consent.
That wasn't the question vaudine asked. The question asked was:
Anyone--if the Speaker ever became Pres. would he/she get to serve until the next election, or would there be a special election?
And I would like to know the answer, also.
I dare say that somewhere in the White House there is a folder with one name in it. If anything happens to the VEEP, that name is sent to the Senate within hours. You might muck about with the Supreme Court, but you don't fool around with succession.
