I don't know what to make of Kagan given her lack of a record since she has not been a judge before. She seems to be a bit of a vague enigma or possibly the mystery prize at the bottom of a box of cracker jacks. You have to buy the box, open it and eat the candy before you get to see what you really picked and got as the mystery prize that was previously buried underneath sugary caramel coating.
It will be interesting to see how the confirmation hearings go with this nominee. Hopefully there will be some efforts to ask good questions and get a better picture of Kagan's judicial philosophies and leanings. I think we really need to know more about this woman before she gets a stamp of approval.
I do have reason to be a bit leery about her. It's nothing super convincing, but it is a sign. Whenever Fox or MSNBC news discusses her and they show a picture of Kagan my dog starts growling and barking at the TV. My dog only growls and barks at the TV for a few things, another being when Pelosi is talking.

Seriously, my dog has to be more politically informed than most voters. She sits on the couch all day watching Fox news and MSNBC news. If you leave her in the room with the TV off, she will turn it on and tune it to Fox news! I kid you not, she has done that several times!
