Fuck.
Kagan is a terrible, but predictable, choice. She's as careerist as they come, has practically no discernible record, is obsequious to power and claims of expanded executive privilege, and will move the court further to the right when Obama should so obviously be using his majority to move it to the left (especially after Roberts and Sc'Alito and with the departure of the court's most liberal member) or at least keep it status quo.
This is another sad day for progressives, who Obama continues to let down.
What makes the move so particularly dunderheaded is that Diane Wood was also at the top of the list of potential nominees, has a long and sterling record, is an appropriate replacement for Stevens in terms of their rulings, is an actual federal judge with plenty of judicial experience and progressive credentials, and would have had an easier confirmation.
