Jeremy Corbyn hasn't said he'd 'certainly' win it,he said probably.
Theresa May did do just enough to ensure being able to hold onto power.
Her expectation of a far greater win was dashed admittedly.

Neil Kinnock never had Labour decisively ahead, also John Major, came out a pretty good campaigner in 1992.

Confidence however does come through at times too.
Blair knew he'd win in 1997,2001 and 2005 and did so.
This govt. looks a fair bit like the last Major led one.

A lot going wrong,hard issues ahead,scandals and a leader being tolerated rather than strongly supported as Mrs May is just being tolerated.

The last election showed a split between seeing how things go as to the status quo,and the change offered from Corbyn's Labour.

The first real defining opposite choices for decades as to the main 2 parties.
It appears as newer voters come to the age they can vote,that more of them want the change, not the status quo.
I can see why Corbyn can feel he can see he can be PM in an election coming early with a probable,not certain Labour win.
He still shows caution in his hopes.
