From my understanding, Pence was a radio host and has been involved in politics of his belief and of religious faith. Trump has done more to stop the persecution of Christians then any President in many decades. It came to the forefront with Obama as the progs were outed as frauds and haters to people who are real Christians. So if Pence does not support Trump it will be a disappointment and whatever he has tried to promote in his life, it will be failure for not at least trying. It takes courage for those who are not the real power. You Progs are the power with the deep state and that includes many Repubs.Pence has been a Tremendous Vice President, I suspect he'll stay onboard if he has any thought of being on the 2024 ticket. Trump isn't going to turn on Pence like McCain did with Sarah Palin.
My thoughts are that President Trump will use the attention of Inauguration Day to launch his 2024 campaign. Starting it early will have the advantage of being able to provide thoughtful critiques to Sleepy Joe's performance every step of the way.
donny will be doing to pence what he did to jeff sessions.
