Republican U.S. Representatives Eric Cantor, Paul Ryan and Kevin McCarthy are all in their 40′s.

Yet with many of their colleagues far older — in their 60′s, 70′s and 80′s — see themselves as “Young Guns,” part of a new breed of Republicans ready to challenge their Grand Old Party and take on Democratic-led Washington.

“Young Guns: A New Generation of Conservative Leaders,” is the title of their book.

Published by Simon & Schuster, it’s to be on book shelves on September 14 in advance in advance of the Nov. 2 election that may see Republicans win control of the House from President Barack Obama’s Democrats.

“We’ve seen both parties ignore the needs of Americans while they concentrate on doing favors for the special interests that get them elected,” Cantor writes in his section of the book.
