LITTLE ROCK, Ark. (AP) -

Democratic gubernatorial hopeful Mike Ross has raised more than $540,000 in the final months of 2013 in his bid for Arkansas' top office.

The former congressman's campaign said Wednesday that he ended 2013 with $2.5 million cash on hand and had raised $3.65 million since announcing his bid in April. Wednesday is the deadline for candidates to file their fundraising reports for the quarter that ended Dec. 31.

Ross is the only Democrat seeking the state's top office. Democratic Gov. Mike Beebe is barred by term limits from seeking re-election this year.

Former U.S. Rep. Asa Hutchinson, state Rep. Debra Hobbs and Little Rock businessman Curtis Coleman are seeking the GOP nomination. Hutchinson announced last week that he raised more than $445,000 during the quarter.
