Democrat Bill Thompson had the biggest haul of all the mayoral candidates this filing period — but because of the city's campaign finance rules, those numbers are deceiving.
Thompson may have gained the most with $600,000 more in the bank, according to campaign finance reports filed Wednesday, but other mayoral contenders have already maxed out.
Christine Quinn, Bill de Blasio and John Liu already raised the max they can spend in the primary, assuming they qualify for public matching funds. That's a looming issue for the Liu campaign, given the conviction of two former campaign associates.
Republican Joe Lhota had the second highest tally this period, raising more than $500,000. He continues to bring in a lot of big checks - but not the small-dollar donations that would qualify him for matching funds.
