Who had the "Worst Week in Washington"?

It's been an eventful and exhausting week in official Washington.

The tragic shootings in Arizona have set off a national debate about the tone of political discourse in the country -- a back and forth that has President Obama and former Alaska Gov. Sarah Palin at its center.

Given the somberness of the week, picking the person, place or thing who has the absolute "Worst Week" is a difficult one. But, pick we must.

So, if you have a nominee, either post it in the comments section below or tweet it out with the hashtag #worstweek.

We'll reveal the "winner" in this space tomorrow.
