I'm hoping the silent few have seen through May's bullshit of late. Openly lying on TV.
Yes, a labour representative couldn't do large scale mental arithmetic whilst under pressure on live TV/Radio but the flip side of that is Tory representatives "hiding" true costs (manifesto) they intend to cut from public services, whilst screaming incompetence at people like Abbott. Give me someone who can't add up large sums under pressure accurately over someone snidey enough to deliberate deceive the mass population about their agenda, any day of the week.
Diane Abbott bless her, has done some incredible stuff in her lifetime (and in politics) but is getting hounded as a "bumbling fool", in the name of votes. Please read this. You might even feel slightly guilty.
