Jeremy Corbyn was a hit when he addressed hundreds of people in Sparkbrook, Birmingham, over the weekend.
There were cheers when he told his audience: 鈥淲e are living in an increasingly brutalised and unfair society. Labour must, can and I believe will be able to offer something different and something better.鈥
But the left-winger, who began the leadership contest as an outsider but could end up winning, is not such a hit with Labour MPs.
He has supporters within the Parliamentary Labour Party, of course. But he couldn鈥檛 even obtain the 35 nominations needed to take part in the contest without help from MPs who don鈥檛 actually intend to vote for him.
And now that it looks like there鈥檚 a real chance of him winning, there is a concerted effort by some MPs to try to halt his progress - and concern that he won鈥檛 be able to command the support of his party in Parliament if he does get in.
It remains to be seen whether the level of support in the Bordesley Centre, a Birmingham community hall, will be reflected in the result announced on September 12, once the votes are all counted.
Some opinion polls suggest he is in the lead. But the ballot is open to Labour members, registered supporters and members of affiliated organisations such as trade unions who choose to sign up as supporters, and there鈥檚 no list of their names and addresses available to the polling companies.
Mr Corbyn himself has pointed out that it鈥檚 hard to see how the polls can be based on reliable data.
It鈥檚 clear, however, that his opponents are taking him seriously.
"A generation in the wilderness"
Birmingham MP , Labour MP for Erdington, wrote a piece in the New Statesman magazine designed to appeal to Labour activists attracted to Mr Corbyn鈥檚 left-wing stance of saying "no" to austerity and taking on the banks.
It鈥檚 not good enough to insist you have the right policies if the electorate disagrees and refused to elect you to government, Mr Dromey said. He warned: 鈥淚t cannot be right that ever again we preside over decline, comfortable and preserving our credentials.鈥
Speaking to me, he said: 鈥淵ou cannot simply say that we are right and the electorate are wrong. That is a certain recipe for a generation in the wilderness.鈥
"End the madness"
Former Home Secretary Alan Johnson, who like Mr Dromey is backing Shadow Home Secretary Yvette Cooper鈥檚 campaign to become Labour leader, wrote an article urging Labour to 鈥渆nd the madness鈥 over Mr Corbyn.
It鈥檚 not a coincidence that on the same day as these two politicians published articles, well-known Guardian columnist Polly Toynbee, also a supporter of Mrs Cooper, published a piece urging the party not to accept Corbyn.
These were deliberate interventions. But other MPs have also expressed concern about the prospect of Mr Corbyn winning.
"Difficult to command discipline"
Black Country MP Tom Watson (Lab West Bromwich East) warned Mr Corbyn could struggle to command the loyalty of Labour MPs because he had been so disloyal to leaders in the past.
He said: 鈥淚t would certainly be a difficult thing for him to try and command discipline within parts of the Parliamentary Labour Party.鈥
Mr Watson, who is likely to become Labour鈥檚 next deputy leader, has not come out in support of any of the candidates for the leadership. This was not a deliberate attack on Mr Corbyn but simply his answer to a question on the subject during an interview with The Huffington Post.
Arguably, though, that does even more to highlight the real fear some Labour MPs have about what could happen to the party if Mr Corbyn wins.
"Greens, Tories and Communists voting in our election"
Birmingham MP (Lab Selly Oak) has expressed concern about the way the leadership contest is being conducted. Anybody, more or less, can have a vote if they sign up as a 鈥渞egistered supporter鈥 by noon on Wednesday August 12. It costs 拢3 and it鈥檚 as simple as sending a text message.
He said on : 鈥淚 find it peculiar that people voting against Labour only 12 weeks ago are now electing our leader鈥, and suggested some of Mr Corbyn鈥檚 supporters may have voted 鈥淕reen, Tory or any variant of Socialist/Communist just a few months ago鈥.
"Tories would love Labour to be led by Corbyn"
Black Country MP (Lab Dudley North) has warned 鈥淭he would love Labour to be led by Corbyn鈥 and said he was 鈥渟cared of what would become of us if he won鈥.
Pat McFadden, Labour MP for Wolverhampton South East, retweeted a comment from a journalist who stated: 鈥淛eremy Corbyn鈥檚 candidacy has shown us who are the genuine left in 海角视频 and who are the fake left- and how thoroughly nasty the latter group are.鈥
So what happens if Mr Corbyn wins? Mr McCabe has said: 鈥淚鈥檒l accept outcome of election and try to support whoever wins.鈥
No doubt many other Labour MPs will take the same approach.
But following May鈥檚 election defeat, a number of Labour MPs on the right of the party lamented that they had made a mistake in keeping quiet when they believed former leader was taking the party in the wrong direction - and vowed not to make the same error again.
