Tbh, the person who never tweeted anything stupid hasn't tweeted. It's been deleted, but looks like she might have been responding to a constituent and adapted her style to suit. No doubt she will learn the error of her ways, but she's been there for 25 years so she's a hardened campaigner.
I am much more interested in Chuka Umunna. I've only seen him a few times, but he potentially could be the future.
