Would you keep this politically charged friend or run?

My BFF of 16 years is not tolerating my husband's political views. They don't have any political discussions but yet she is very aggressive about it. Because of that I was disinvited from my own birthday that she was organizing for me on the beach. My hubby is tolerant of any political views and you can have conversation about anything with him. He was always respectful etc.

Also my other friend told me that when she got drunk, she got very angry said that she will "f*ck him up" for his views when she sees him next time. I don't think she remembers what she said because she blacked out, I wasn't present in the situation. I don't think she knows that I know nor she remembers what she said. I saw her few days before that and she was acting nice and normal like we still are seeing each other on the beach for my bday.

There was also other situation a month ago where we have been planning a group trip for 5 moths. She was ok 3 hours before she arrived, then all the sudden she pretended she doesn't know us, because my husband wore a trump hat. She was sleeping at the camp site next to us, didn't say "hi", didn't stop by, she wrote me some angry texts at night when she got drunk again. A week later, we had "the talk" to clarify (initiated by me, not her!) and it seemed to me that we were cool until my bday surprise. I hate to give up on my BFF but I don't know how to reason with her anymore (she's 38).
