Pushing toward big gains on Nov. 2, House Republicans promised to end a slew of Democratic policies and restore Americans' trust in government as they rolled out a campaign manifesto designed to show they're listening to an angry public and are focused on creating jobs. "The land of opportunity has become the land of shrinking prosperity ... Our government has failed us," Rep. Kevin McCarthy of California declared. "We will take back our country. We will restore for a better future. This is our pledge to you."At a hardware store in suburban Washington, senior House Republicans in shirt sleeves showed off the 21-page document they say would guide them should they gain a majority of seats in the midterm balloting five weeks away. The "Pledge to America" was filled with familiar proposals to slash taxes and spending and cut down on government regulation, as well as repeal President Barack Obama's health care law and end his stimulus program. In a show of unity, Senate Republicans and Haley Barbour, chairman of the Republican Governors Association, issued strong statements of support.
