Gas prices have skyrocketed and the 36th annual Earth Day just passed. So it's hardly surprising that many Democrats have taken the opportunity to bash the president's environmental and energy policies. Senator Minority Leader Harry Reid has demanded a "bipartisan national energy summit to solve the problem of America’s dangerous dependence on foreign oil...." And Sen. Bill Nelson of Florida delivered his party's radio address on Saturday. He urged a higher "mileage standard for all passenger vehicles," which is interesting because Democratic Sen. Carl Levin has often led the charge against stiffer mileage standards. Nelson further warned Americans, "We must confront some powerful interests, including the oil lobby" if we our to cut our "dependence on foreign oil."

Like Sen. Nelson, Greenpeace is also confronting "some powerful interests." According to the National Journal, the group has taken on the Senate's premier liberal for his opposition to a proposed wind farm that "would provide 75 percent of the area's energy needs with clean and safe wind power."

Greenpeace takes on a surprising target this week: Sen. Edward Kennedy, D-Mass.

The 30-second spot features a cartoon Kennedy pounding wind turbines as they sprout from the water. A voice meant to be Kennedy's -- but lacking the senator's trademark New England drawl -- complains that "I might see [the wind farm] from my mansion on the cape!"

Kennedy recently backed an amendment to a Coast Guard reauthorization bill that would make the first offshore wind energy project vulnerable to state veto.

Of course, I don't blame Sen. Kennedy (or Sen. Kerry for that matter). I wouldn't want to sit on the porch of my beachfront mansion staring into a sea of turbine generators either.
