And so is politics where what's achieved today can be undone tomorrow. Some time it's the role of the courts to roll back laws and policies that are unconstitutional. That's what happened this week with The Bush Administration's warrantless wiretaps. Appeals are likely to be filed to undo what has just been undone.
As Casey Stengel once put it famously, "it ain't over till its over."

Here are two examples reported by Media Matters for America.
"McGuirk's remarks were just the latest attack against Lamont, the Democratic nominee for a Connecticut Senate seat. As the weblog Think Progress noted, on the August 16 edition of Fox News Live, former Weekly Standard deputy publisher David Bass said that a woman who caused a plane to be diverted after suffering a panic attack was "probably not a terrorist; could just be a Ned Lamont supporter."
Sometimes, when called on their sloppiness and lack of professionalism, TV hotshots will admit they blew it. My colleague Judy Newman was outraged by the "terror baiting" of Ned Lamont, the cable news "red meat" target of the week. A reader protest prompted a response and "apology" to Ned Lamont from Chuck Roberts:
