Accused campaign-cash crook John Haggerty failed yesterday to convince a judge to toss his charges, instead earning a judicial scolding for arguing that he’s really just a nice guy.

As first reported in The Post, Haggerty allegedly talked Mayor Bloomberg into contributing $1.2 million to the Independence Party in late 2009, then pocketed $1.1 million.

Haggerty had argued that the case against him should be thrown out because he has spent his professional life working for government officials, is a loving family member, served as an altar boy and once considered becoming a priest.

But “the bottom line is that [Haggerty] sought to enrich himself at Mayor Bloomberg’s expense,” Manhattan Supreme Court Justice Ronald Zweibel wrote in his ruling allowing the prosecution to proceed.
