Elena Kagan's platitudes in front of the Judiciary Committee today were more than Senator Al Franken could tolerate.

"We don't have any substantive evidence to demonstrate your ability to transition from a legal scholar and political operative to a fair and impartial jurist," Sen. Charles Grassley (R-Iowa) told her. Beyond that, Republicans made it clear they will grill her this week on a series of issues, including gun rights, illegal immigration, same-sex marriage, and campaign-finance regulation. While Sen. Dianne Feinstein (D-Calif.) called Kagan's lack of judicial experience "refreshing," at least one Democrat, Sen. Herb Kohl (D-Wis.) noted that Kagan's judicial philosophy "is almost invisible to us." Kagan, 50, has served as the government's lawyer before the high court for the past year. Beyond her work in the Clinton White House, she is a former dean of Harvard Law School and the majority of her career has been spent in academia. She's the youngest nominee to come before the committee since Clarence Thomas in 1991.
