Kentucky Attorney General Jack Conway (D) ended 2009 with about $1 million more in his Senate campaign war chest than his top primary rival, Lt. Gov. Daniel Mongiardo (D).Conway had $1.7 million in cash on hand on Dec. 31 while Mongiardo had about $783,000 in the bank. But the money race between the two Democratic rivals was much closer when it came to fourth-quarter fundraising. Conway raked in about $333,000 from October through December, while Mongiardo raised more than $225,000 in that time period.As often happens with October to December fundraising, those totals are down from the candidates’ quarterly hauls from earlier in the year. Conway raised $675,000 from July to September while Mongiardo raised $514,000. Mongiardo raised just $303,000 in the second quarter of 2009, a paltry amount compared with Conway’s $1.3 million haul.The two men will meet in a May primary to decide who will head to the November election. The winner will almost certainly face either Secretary of State Trey Grayson (R) or anti-tax activist Rand Paul (R).
