other than Pence are there any other feasible options if DT is impeached, and someone worse like, I'm thinking in particular of Bannon, couldn't become president could he? [cowers in fear at the thought]
The order of succession is Mike Pence (arguably far worse than Trump), Speaker of the House; Paul Ryan - (Republican fan of Ayn Rand, but slow to endorse Trump when he won the nomination, Roman Catholic which is certainly less crazy that the Southern Independent Fundamentalist Baptist movement). Then Senate Presdient; Orrin Hatch - (Republican, Mormon, anti-gay not as bad as Pence). Then Secretary of State; Rex Tillerson - (Republican, Protestant, has helped end discrimination against gay boy scouts, ties to Exxon and Putin, supports Saudi Arabia). Then Secretary of Treasury; Adam Szubin - (Democrat, Jewish, Harvard educated lawyer, worked for Obama administration.) And on down throughout the various secretaries.
On the off chance America falls foul to a Y The Last Man type of catastrophe the first woman in succession is ineligible as she was born in Taiwan, the second will not hold the office for long as she is just a stand in for Rick Perry. And the next is Betsy DuVos, so that will be marvellous.
