Kasich and Pence will win but unless the Dems put up a shitty candidate (which is entirely possible) they are both better off waiting until 2024. If Trump does run again (I'm doubtful) it will be Kasich or Graham running against him plus Evan McMullin. But neither of those 3 will win
I really like Kasich. If a Republican had to be president, that's the best guy they could put in the Oval Office, in my opinion. While I wouldn't vote for him (unless trump got the Democratic nomination, ha ha), I have a lot of respect for Kasich and wouldn't feel like he would place our country in danger, which is what trump is busy doing, as well as a load of other gross stupidities.
It may be the best move for the country to elect a moderate conservative like Kasich. We are so damn divided.
