When the Prime Minister called for a General Election on April 18, Jeremy Corbyn was seen by many as the outsider; unfathomable that he might come close to Downing Street.

This morning The Times published a YouGov poll, predicting a hung parliament.

The poll predicts that Mrs May will walk away with 310 seats, and Mr Corbyn 257 seats.

That is a 20 seat loss for the Conservatives and a gain of 25 seats for Labour.

326 seats are required for an outright majority.

It’s necessary to remember that this poll is one of many; many of which are predicting a comfortable Tory majority. However, to think how unimaginable it was that the man who for decades was a Labour rebel might diminish the majority of the ‘Iron Lady’ of the 21st century – it’s a landmark moment for the election campaign.

Back in April, Corbyn’s campaign launch had populist, Trump-esque undertones. He attacked the elite and the media, vowing to run a government “for the people”.

In recent weeks the race for Downing Street has created parallels with last year’s U.S. election.

Trump: the outsider, the underdog, the enemy of the elite managed to win his way to the White House.

Meanwhile Hillary: the longtime politician, the overqualified establishment choice was forced to say goodbye to her dream of becoming America’s first woman president.

The comparisons are strikingly easy to make, even if the policies of Trump and Corbyn are nothing alike.

When former U.S. first lady Hillary Clinton announced her candidacy for the 2016 presidential race she was almost seen as certain to win, even without it being clear who she would be competing against.

On the steps of Number 10 back in mid-April, Prime Minister May announced the General Election and the national media and vast swathes of the public assumed we were in for a landslide victory for Britain’s second woman Prime Minister.

In recent weeks Theresa May’s lead has narrowed, a Good Morning Britain/Survation poll projected only a six per cent gap between the Tories and Labour. Her ‘strong and stable’ mantra has come under fire as she has ducked away from election debates and committed a high-profile u-turn on social care.

What once was looking like the inevitable is now looking less and less certain. Jeremy Corbyn is gaining ground.

The ‘Grime 4 Corbyn’ movement epitomises the admiration felt towards him by youth voters.

Celebrities – from Ronnie O’Sullivan, to Danny DeVito and Stormzy – have given Mr Corbyn their endorsement and his opinion ratings have gone up and up.

With less than a week to go until ‘decision day’, what was at first seen as one of the most boring General Elections in decades, is finally getting interesting.

In the U.S. race, Hillary Clinton’s disconnect from large groups of voters meant that she was reliant on Trump being ‘un-electable’.

There was little excitement from the American electorate about Hillary’s candidacy, in vast contrast with the zeal of Trump’s core base.

This is reflected in Theresa’s campaign. There’s little enthusiasm with her base, in vast contrast to the ‘Corbynmania’ that has awoken the left.

Mrs May is reliant on the apathy of young potential voters who might buy into Corbyn’s vision of a nation ‘For the Many’.

In 2015 those who did not vote vastly outnumbered those who voted either Tory or Labour; and David Cameron’s majority was genuinely a surprise for almost anybody who had been paying attention to the state of the race.

Electoral shocks are nothing new. Cameron, Brexit and Trump all shocked the world and are evidence that a Corbyn win is not impossible.

If the Prime Minister wants to avoid being the Hillary of Westminster she needs to eject something, anything, that projects a positive vision of Britain under her leadership.

Jeremy Corbyn’s optimistic vision of a nation ‘For the Many’ connects with those disillusioned after seven years and two administrations worth of Conservative austerity.

When Donald Trump announced his candidacy for the Republican presidential nomination in the summer of 2015 the majority of America felt it unfathomable that he would get close to the Oval Office.

On the morning of April 18, Prime Minister May addressed the nation on the steps of Downing Street and announced she was calling a ‘snap election’. The general consensus across Britain was that there was no way Jeremy Corbyn could be stood in that same spot giving a victory speech on June 9.

Seven weeks into an eight week campaign; it’s looking a lot more possible that Prime Minister Corbyn might be leading Britain through the next five years.
