In a new book to be released next month, three House Republican leaders include many of the policies and ideas that some in their party have promoted over the last year, as well as a controversial plan to drastically cut the countrys entitlement spending.The proposed entitlement overhaul by Rep. Paul Ryan (R-Wis.), known as the Roadmap for Americas Future, is featured with many GOP solutions for the debt, national security and health care in Young Guns, according to an early edition of the book obtained by Roll Call. Ryan, Minority Whip Eric Cantor (R-Va.) and Chief Deputy Whip Kevin McCarthy (R-Calif.) wrote the book.The three divided the majority of the writing into separately authored sections, but the inclusion of the entitlement plan indicates an implied endorsement by at least some of the GOP leadership. Neither Cantor nor McCarthy is among the bills 13 co-sponsors. Ryans proposal, which looks to balance the budget through slimmer versions of Medicare, Medicaid, Social Security and the tax code, has vexed many Republicans who have attacked Democrats over the federal debt but who dont want to say they would favor cutting entitlement programs.Its time we stop deferring tough decisions and promising fiscal fantasies, Ryan wrote in the book. Its time we tell Americans the truth, offer them a choice, and count on them to do whats right.Ryan is the ranking member of the House Budget Committee and would likely become its chairman next year if the GOP reclaims the House majority in November.During a conference call about the economy Monday, Ryan told reporters that the road map was his solution to the entitlement problems, not that of the House Republican Conference.
