You really don’t know how US senators and the US Senate operate, do you?
Yes, yes I do. Senators aren’t just off writing their own speeches - they look at drafts and ask for tweaks, give a very general guideline, etc.., but they don’t take time to write speeches. Hell, they don’t write the legislation that they sponsor (in large part their aides do that).
What makes you thinks she sat and authored the speech all by her lonesome?
it’s silly to think that this wasn’t a concerted effort and she was simply the vehicle chosen to deliver the statement. She may agree wholeheartedly and have had input, but she wasn’t the sole author of it - no bloody way!
