She's the only one telling the British people what she's not willing to accept from the EU.
Those two aren't the same thing. You're not going to accept certain terms? Great, not outline what you are going to do.
When?
There was her trip to India ("underwhelming"), holding hands with a leader like a hapless housewife, and then the awfully transparent meltdown about the EU meddling in the British election. Dress it up all you want on that last point - they got to her. Points scored for the EU.
Weak?
She, as home secretary, said she'd reduce migration, but couldn't deliver because membership to the EU meant that membership rules and regulations gave her no chance of reducing migration. She said there wouldn't be a snap election, but when she (in January) said that "no deal would be better than a bad deal", opposition MPs came against her' leaving her no choice but to go to the people for greater support.
How does any of this prove she isn't weak? It certainly doesn't make her look strong, and since that's all you could realistically be attempting to do in order to refute my claims, you'll have to do better on that one.
The biggest blunder from the tory manifesto was the social care tax, which I also disagree with. Other than that, how is she weak?
Backtracking on policies, spectacularly blowing a comfortable lead in the polls, stumbling through answers when challenged away from a studio setting, being scared to venture away from scripted soundbites, all of the aforementioned problems on the world stage. Weak! Listen, she might be your darling in this election and I'm sure you're having a good time bashing the fervent Corbyn supporters, but she's just not a good leader. You'll have more luck pissing on my leg and convincing me it's raining.
