(POLITICALTICKER.BLOGS.CNN) — Could former Rep. Anthony Weiner be preparing for a political comeback?

The Democrat’s latest filing with the New York City Campaign Finance Board, published Tuesday, may send some subtle messages.

His mayoral campaign committee, created ahead of his unsuccessful bid for the Democratic nomination in 2005, reported spending just one dollar shy of $37,000 in the last six months. It brought in $27,400 in the same period, largely through a transfer from a previous political committee.

Should he decide to run, Weiner now has nearly $4.5 million cash on hand – a start for a mayoral run in the Big Apple. Mayor Michael Bloomberg spent over $108 million on his successful 2009 bid for a third term, according to the campaign finance board records.
