If JC and TM have the same popularity now then you are saying that on her worst day TM is as good as JC on his best day. So why should JC be 'gifted' No 10 when he lost the election by quite a margin of seats and votes? Surly JC should stand down for missing such an open goal, in favor of someone who could have actually won the election.
Neither the DUP nor the Conservatives will call another election for nearly 4 years, JC supporting Brexit a lot can happen in that time.
I know several people who voted Labour as a protest, 'safe' in the belief that the Conservatives would win. But would never vote for Labour, now there is a danger JC could actually win.
I also know some people who didn't go out of their way to vote because the outcome was perceived as a forgone conclusion. Now their is a danger of JC winning they will go out of their way to vote to stop him getting in.
More than 68% of the young people that don't go to university might awake to the reality that JC would make them to pay the £30k+ a year for the other 32% of young people to go to university and get better paid jobs.
JC is no longer the underdog. The Conservatives will get, I hope, a younger more charismatic leader with a more sensible manifesto. JC is great at protesting but shows no sign of leadership other than massive monetary give-aways to young middle class voters with no credible plan on how to fund them.
Massive rises in the cost of living, lots of stealth taxes, unemployment, strikes... are all likely if JC was ever PM. Hopefully his manifesto will be properly debunked before the next election or if your leaving the UK you dont need to turn the lights out as we wont be able to pay the bill to have them on.
It all leads me to conclude Corbyn will never win a general election and we will have another coalition at the next election.
