She's in the position the president is often in: some people take her literally, but not seriously, and others take her seriously but not literally.
If you take her literally, she's lying and you hate her (or if you already hate her, you take her literally). She opposed Trump when he was going for the nomination, and she must have questioned his fitness for the office at that time, certainly privately, and probably publicly as well.
If you take her seriously, as saying that since he was elected and she was appointed she has been a loyal employee and hasn't publicly questioned his fitness for the office or conspired against him, then who knows? She might be right about that.
It's common in politics that people in the same party fight it out before the nomination. What matters is what happens after the nomination and after the general election.
Is she trying to replace Pence? Yes and no. She might want to take the nomination away from him in 2024, but I don't think she wants to be the VP nominee in 2020. Even if she's loyal to Trump, there is some tension between them and her patience and her nerves wouldn't survive the daily stress. Pence doesn't get as agitated or frazzled by all the ups and downs.
And at this point, it's not that people haven't heard enough about "natural born citizenship," it's that they've either heard too much or not liked what they've heard.
Excellent summaries!
I found myself nodding in agreement through most of it.
One should never forget that in politics just like any other part of civilized life, people often change over time.
I used to be a Democrat, brought up in such a home.
I stayed that way until after the Rodney King incidents of 1991. After that, I questioned my leadership.
