I give you Dan Froomkin:

The White House and the Republican leadership believe embracing the president's warrantless wiretapping program and detainee proposals are key to surviving the November elections.

But the effects of the legislation Congress is considering this week will last far beyond November. And critics argue that the White House's approach won't help protect the country so much as put captured American soldiers at risk, further blacken America's image abroad, legitimize unconstitutional treatment of detainees, erode privacy rights, cede congressional authority and institutionalize what has thus far been the extralegal assertion of nearly unchecked, and therefore potentially corrupting power, to this president as well as those to come.
