GLASS HOUSE WATCH. Larry Kudlow at National Review Online:

Is it just me, or has anyone else noticed Hillary's erratic, roller-coaster, mood swings these past few weeks?

She's all over the map. Irritable and angry. Manic. Pessimistic and sad. One minute she's shedding tears, the next minute she's shouting and attacking, then she's sarcastically ripping on Obama, and on and on it goes.

So, is Hillary depressed?

Now I'm no psychiatrist, far from it, but I think a simple answer is that Senator Clinton could be depressed. She seems deflated. Down in the dumps.

Look, depression is a serious problem. It's also a multibillion-dollar business. Three of the more popular drugs in the market today to treat it are Pfizer's Zoloft, Eli Lilly's Prozac, and GlaxoSmithKline's Paxil. Maybe Hillary's taking meds, but they're just not working for her? Could that be why she's always attacking Big Pharma?

Maybe she just needs a little toot to get her over the hump. Perhaps Kudlow can pull out his old rolodex and hook her up.
