Senate Republicans will host a major fundraiser next week for Michigan GOP Senate candidate Terri Lynn Land, an indication that the party believes it has a chance of seizing an open seat in the traditionally blue state.

Senate Minority Leader Mitch McConnell, R-Ky., will headline a National Republican Senatorial Committee fundraiser in Washington on Nov. 19 to benefit Land, the likely Republican nominee to face Democratic Rep. Gary Peters for the seat being vacated by long-time Democratic Sen. Carl Levin.

Eleven other high-profile Republican senators will join McConnell, including John Thune, of South Dakota; Rand Paul, of Kentucky; Marco Rubio, of Florida; and Rob Portman, of Ohio, according to an invitation obtained by the Washington Examiner.

The minimum contribution to attend will be $1,000 for individuals or $2,500 for political action committees.

Land has been holding her own in fundraising and recent polling against Peters, although Peters enters the race with a pronounced edge in Democratic-leaning Michigan.

Republicans have been cautiously optimistic about the outlook for Land, and NRSC Executive Director Rob Collins insisted last week that the party is taking the Michigan Senate contest seriously.

"Michigan is a tough state presidentially, but in an off-year in Michigan, Republicans can win," Collins said.
