1. In one of my Six Clicks yesterday, I refered to Joe Klein as "Joel Klein."

2. Twice I referred to Illinois Gov. Pat Quinn as "she." Mr. Quinn is unambigiously a male.

3. I repeatedly (and even in an earlier version of this post) misspelled the name of RNC chairman candidate Chip Saltsman. 

4. In an early version of a post, I said that it remained uncertain whether Justice Ginsburg's cancer was malignant; all cancers are malignant. As the son of an oncologist, I should know this.

I apologize for all these errors; I take them seriously, because they make me look stupid. That said, there will be more, and I ask for your forbearance in advance.
