How is anyone comfortable with Trump staying in office?

There's nothing to be done. He's not going to be impeached and removed from office and if it didn't work before, it certainly won't work before the election. So comfortable or not, the next chance is the election. If you're not comfortable with President Trump then you need to vote them out.

If he's voted out then problem solved.

If he's not then you have two more chances depending on if Democrats get more power in Congress both in 2020 and 2022 and if they impeach and remove him this time (though a lot depends on Republicans). Those are the other two chances for him to stay in office and then 2024 is his final year.
