WASHINGTON (AP) — Democrats tried to drum up support for compromise legislation on offshore drilling on Saturday, challenging Republicans to break from Bush administration policies that neglect development of alternative energy sources.”Enough is enough,” Sen. Ken Salazar of Colorado said in the Democrats’ weekly radio address, citing rising energy prices, including $4-a-gallon diesel fuel. “President Bush and Sen. McCain have failed to show any leadership on this issue for the last eight years,” Salazar said.
