I don't think they have all that much to work with:
Republicans — who have not ruled out a filibuster — will seek to define Kagan through her liberal associations to paint her as an activist who would write new laws from the bench.
“You have to ask who she admires, who she identifies with, who she supports, who she worked for,’’ said Sessions.
There's also this:
Judiciary Committee member Sen. John Cornyn (R-Texas) wrote in a column Sunday evening that "it is reasonable to worry that [Elana] Kagan is a judicial activist simply because President Obama nominated her."As Steve Benen points out, this logic is refreshingly circular.
Sigh, it's going to be a long day.
To make things easier, I have condensed today's hearing into a word cloud, using the entirety of Senator Cornyn's USA Today column.
