Stuff like this is what makes the Lib Dems a total joke - a party supposedly appealing to the centre, but who in reality are only ever happy to side with the Tories. Wolves in sheeps clothing
Siding with the Tories is wanting to stop the Blues/block Brexit because he criticises Labour?
What?
Also it was not Corbyn calling for the seizing of private homes - it was an unusually daft comment from David Lammy, who should know better.
Corbyn/McDonnell policy is mostly associated with big numbers that don't add up but get folks accused of Fake News for criticising. A lot of the money they want to spend would be on re-nationalising industries without any real plan for what they'd do after that, too.
Labour is in a barmy place right now for quite a lot of reasons, really. A moderate but expensive manifesto at the last election, a crippled Tory party and only evidence of a slight actual lead that would leave them far from solo power now and they face the risk of a de-May'd Tory party resurging, especially in Brexit-y places Labour cannot afford to lose. They, and by that I mean Labour, would be in a better spot right now if they had a leadership that was less hard left as it would be more attractive to the centrists and even remainers on the right who are fed up with the Tories.
