Baroness Warsi has had enough of Leave's "hate and xenophobia" and decided to switch to Remain. Farage's 1930s poster strikes me as a misstep. Those who might be persuaded by it were already voting Leave, floating voters are more likely to be put off by it than drawn in by it and it is those voters than Leave needs.
From my point of view, more Farage please!
vote leave tweeted saying they didn't know she was campaigning, I certainly haven't seen anything from her.
