Lovely statements and all, but high on preconceived biases, short on reasoning.
UKIP if they actually win any seats next time will be taking them off the Tories, not Labour.
Many floating centre voters will likely vote Lib Dems' next time. The Lib Dems natural position is around 40 seats and they should get back to something approaching that next time - the vast majority of those gains will come at the expense of the Tories - because that's who they lost most of their seats to last time and that's where they're most likely to get them back.
The next four years will be as challenging as anything any UK government has ever had to deal with since World War II with the Brexit negotiations likely to go badly and Scotland threatening independence.
If Tory supporters want to assume polls during the silly season when they've just appointed a new PM will be the same as the polls during the Brexit negotiations when things start to badly unravel, that's fine by me.
