Someone said :
Lets hope, If they do impeach him soon and I hope he is taken down by a woman. That Pence may have to resign, due to pressure and a re-election called?
The next election by the people for president is not for four years. If Pence's job becomes vacant, a replacement nominated by the president and is elected by a majority of both houses of congress. That would be the Republican's dream come true: having a president and vice president that they want, over the heads of the nutty membership who backed Trump.
That process is how Ford became president -- he replaced the elected vice-president, Spiro Agnew. Agnew had been forced to resign when he pleaded guilty to a sample charge of not reporting income -- essentially accepting payment for favours, stemming from earlier in his political career.
