A new poll shows the Kentucky Senate race to replace retiring Republican Jim Bunning competitive in both primaries. On the Democratic side, Lt. Gov. Dan Mongiardo leads Attorney General Jack Conway by 39 percent to 31 percent. For the Republicans, Secretary of State Trey Grayson leads Rand Paul by 37 percent to 26 percent. Although down 11 points, that's not a bad showing for Paul, who is a first-time candidate who has only been campaigning for three months. If his "money bomb" goes well this week, the Republican race could well tigthten.
