LOL. Your concern is duly noted and for you to even dare to write publicly that you “wonder if she was under the influence of alcohol” is truly beneath you. Sarah Palin and Donald Trump are close friends. She is well aware that he doesn’t drink. There is no way she would disrespect him or embarrass herself, by showing up “under the influence of alcohol.” Sheeeesh!
I will only add, that he was delighted to see her and delighted by her speech.
I said it because I believe it is possible due to her behavior giving that speech. If it is not alcohol, then I think she is taking something else, and it could be a medicine, several I know of that can change behavior. She was “off” giving that speech. If the next one is like this one, then something is going on with her. If the next one is fine, then this one was an aberration.
