The former politician has become known for his dodgy dad dancing but it's endeared him to the nation.
He's yet to be in the bottom three with many - including pro dancer Brendan Cole - backing him to win.
But backstage and there's said to be a split over feelings towards Ed.
According to The Sun newspaper, producers of the show love the 'ratings' that Ed is bringing to the series but the judges fear he will keep on knocking better dancers out.
"The judges publicly say Ed is entertaining because he is," an insider told the newspaper. "But privately they think it’s making a mockery of the show if he gets to the final as there are so many talented dancers this year."
The source added: "The producers are over the moon he’s still in it and have been congratulating themselves as it has boosted ratings over the X Factor."
Strictly judge Craig Revel Horwood suggested this week that Ed could well get enough public support to make the final.
But he warned the former MP that dropping into the bottom two would mean instant elimination.
“I have a horrible feeling that Ed Balls has enough gimmicks to be the wild card,” Craig told the Radio Times. “I’d give him D for desperate. He is entertaining but has no semblance of technique.
“But Ann Widdecombe got through to week 10, so anything is possible! I mean, he could go on to win it.”
Strictly Come Dancing 2016 continues live this Saturday and Sunday night on BBC One.
