Jeremy Corbyn is used to battling polls that put the Tories far ahead.
But supporters may take a glimmer of hope from one result that came out after last night's first TV clash of the election campaign.
YouGov polled 1,646 viewers after the ITV leaders' debate between Boris Johnson and Jeremy Corbyn .
The pollster found 51% backed Johnson as the best performer while 49% backed Corbyn. But with undecided voters, the result was different.
In that group, 54% said Jeremy Corbyn "performed best overall" in the debate - with just 38% opting for the Tory leader. The rest didn't know.
The results must be treated with caution because they are a 286-person subset of the overall poll - and the lower the sample size, the worse the accuracy.
But former YouGov President Peter Kellner said even if it was just "firming up wavering Labour supporters", it was "still significant".
Among decided voters, the results were stark in the other direction. 51% of the 1,120 decided voters backed Boris Johnson while 44% backed Jeremy Corbyn.
The snap poll also found Jeremy Corbyn performed better on the NHS, with 54% of people's support compared to 38% for Boris Johnson, after he claimed the Tories would put the service up for sale after Brexit .
But Boris Johnson performed better on Brexit - 63% to 27% - after repeatedly questioning Mr Corbyn on his policy not to decide until next year how Labour would campaign in a second referedum.
And after the audience laughed when Boris Johnson said truth was important, the poll found Mr Corbyn was more trustworthy - on 45% compared to 40% for the Tory leader.
It comes after Boris Johnson and Jeremy Corbyn clashed over trust, Christmas presents and Brexit on Tuesday night in the first TV clash of the general election campaign.
Audience members laughed as the Tory leader said the truth was important - despite making a string of dodgy claims and his party trying to style themselves as factcheckers.
Mr Johnson was also quizzed on Prince Andrew after ducking questions yesterday. And he said he'd get Jeremy Corbyn his Brexit deal for Christmas, before settling on a jar of damson jam.
Meanwhile, Jeremy Corbyn shot back at claims he'd stitch up a coalition with Nicola Sturgeon to get into 10 Downing Street.
