Talking to LibDems this afternoon about Vince Cable's proposed mansion tax, I have yet to find more than a handful who support it. The majority say that while they personally find it acceptable, it's political madness. One delegate described it as an "indulgence".
Susan Kramer must be spitting tacks and it's just as well she isn't here this week as she'd probably deck him. Her Richomnd-on-Thames constituency has a lot of houses which fall into that bracket, as Zac Goldsmith will no doubt he highlighting.
To me this has all the hallmarks of becoming the LibDem poll tax. It's also envy politics of the worst find.
