Washington (CNN) -- House GOP leaders unveiled a 2013 budget blueprint Tuesday that has little chance of becoming law but draws a clear contrast with Democrats on taxes, spending, and a host of hot-button political issues -- all of which could play a pivotal role in the 2012 campaign. Republicans cast the $3.53 trillion plan -- which doubles down on past GOP proposals to overhaul Medicare and other politically sensitive programs -- as a bold attempt to reverse skyrocketing federal deficits and avert a looming fiscal catastrophe. "This plan of action is about putting an end to empty promises from bankrupt government and restoring the fundamental promise of America, ensuring that our children have more opportunity than we do," said House Budget Committee Chairman Paul Ryan, R-Wisconsin.
