The only thing to "wonder" about is how Mazie made it this far in life.  Oh...I can tell you.  By doing absolutely nothing of distinction but continuously running when Dan said it was OK and having a "D" next to her Japanese surname.  Nothing to "wonder" about there.

I've worked with Mazie in the past.  Overall, she's nice enough.  She's not terribly sharp, but really relies on liberal talking points and even then starts to get confused if the conversation or rhetoric heats up.  But once you get into politics, she is so rabidly left and horribly nasty to anyone who doesn't agree with her that she becomes impossible to work with.  She's also terribly insecure and has been living in constant fear for years that Tulsi was going to challenge her.  Guess she doesn't have to worry about that now--Colleen will be sitting in her seat in six months.
