Only £966 has been raised out of a £3,000 target, with today the final day for donations.
Mulholland started the campaign last month, with the money raised earmarked for producing leaflets, making phone calls and for further campaigns calling for stronger planning laws and reduced beer duty.
Fellow Lib Dem and pub campaigner Gareth Epps, who is standing against the last community pubs minister Kris Hopkins in Keighley, was among those who donated.
Self-styled ‘pub champion’ Mulholland has been a vocal support of the industry throughout his time as an MP, navigating recent pub code legislation through the House of Commons. He is also a key member of the Otley Pub Club, which became the first town in the UK to have all its pubs listed as assets of community value.
Mulholland is defending a strong Lib Dem strong majority of 9,103 in the constituency of Leeds North West, having first won the seat in 2005.
