As you were frantically typing your reply exactly how I portrayed it, the very first thing you said (after misspelling "She") was made up.
As far as I know Kamala doesn't "support open borders". The Biden/Harris administration kicked out more people than trump did and there has also been record detentions. If droves of people are getting detained and kicked out, the border ain't exactly "open" now is it?
I'm pretty sure I've heard her talking about supporting immigration reform, but idk if "open borders" was part of that.
