WASHINGTON (CNN) -- House Majority Leader John Boehner, who is vying for the top GOP spot when his party goes into the minority in the next Congress, said Wednesday the GOP must rebuild 'the Republican brand' if it hopes to regain its majority.

"To regain our majority in 2008, House Republicans need to get back to our core principles and rededicate ourselves to the reform mindset that put us in the majority 12 years ago," Boehner wrote in an editorial appearing in Wednesday's edition of "The Hill" newspaper. “We must rebuild the Republican coalition by focusing on reform ideas because they will not only win broad-based support among House members, but among the American people."

Boehner is competing for the House minority leadership position with Reps. Joe Barton of Texas and Mike Pence of Indiana. The GOP caucus is set to hold their House leadership elections Friday.
