Five years ago, Moveon.org invited people to post their own homemade ads for the 2004 presidential campaign and submit them anonymously.

Some unknown person, out of over 1,500 submissions, put together an ad comparing Bush to Hitler, and put it on the MoveOn.org site without the group's knowledge. MoveOn pulled the submission.  But it was too late.

The conservatives had a hissy-fit.  Ed Gillespie, chairman of the Republican National Committee, at the time called the anonymously submitted video "the worst and most vile form of political hate speech." Traditional news outlets ran with this, charactering MoveOn as being extremists.

That was all in response to a video submission from an anonymous person.

Contrast that to the present day.

Today — just today — Rush Limbaugh told his audience, "Adolf Hitler, like Barack Obama, also ruled by dictate."

Around the same time today, Glenn Beck tried to link health care reform to Nazis.

And yet nobody takes note.  In fact, everyone from Republican senators to talk-radio hosts to conservative writers makes the Obama-Hitler comparison with such frequency, that there is no controversy about it.

So will some please explain to me why — a mere 5 years ago — an unknown person makes a Bush-Hitler reference, and it causes a firestorm…. but today, prominent conservatives and GOP party leaders can routinely make Nazi comparisons and nobody cares?
