Senate Minority Leader Mitch McConnell, R-Ky., finds himself ahead of his Democratic challenger Alison Lundergan Grimes by four points in a new poll released Tuesday.

Public Policy Polling released its latest poll that shows McConnell with a 44 percent to 40 percent lead over Grimes. Libertarian candidate David Patterson pulled in seven percent of the vote.

Kentucky is key for Republicans if the party hopes to take control of the Senate in November.
