The Foxes were held at the King Power Stadium last night, drawing 2-2 with West Bromwich Albion.
The encounter has already been earmarked as one of the most entertaining of the season thus far, with both sides taking the lead and then coming back in quite dramatic fashion.
Co-commentating on the game for the BBC, Barton was taken in by the intensity around the King Power Stadium and he urges more to jump on the bandwagon and wish Leicester well in their title bid.
"You couldn't wish for a better place to come and watch football. The place was jumping tonight. I can't believe more people in the game don't want Leicester to win the league,” Barton explained at 21:48pm.
“More people need to get on this bandwagon. It will be magnificent for football for them to win it now. I am a Leicester fan from now until the end of the season."
The draw leaves Leicester topping the Premier League table ahead of Tottenham Hotspur by just three points, with Spurs set to face West Ham United at the Boleyn Ground on Wednesday.
Arsenal and Manchester City, two of the other contenders, face Swansea City and Liverpool respectively also on Wednesday in what promises to be an interesting evening at the top of the table.
Leicester seemingly have the belief to win the title, yet a failure to create a gap at the top before they take on Chelsea, Manchester United and Everton in their final three matches could spell trouble.
