Primary election results from Pennsylvania, Kentucky, and Arkansas give a snapshot view of the state of the electorate.
Joe Sestak and Rand Paul defeat incumbents with high-level endorsements.
Rand Paul says he'll stick with his Tea Party-approved anti-federal government message after capturing Kentucky's GOP Senate nomination Tuesday night.
Tuesday's primaries signal a restless electorate unwilling to follow the behest of either party establishment. Sen. Arlen Specter lost in Pennsylvania. 'Tea party' pick Rand Paul is GOP's Senate candidate in Kentucky. Sen. Blanche Lincoln faces a runoff in Arkansas.
The Tuesday primaries will be dominated by four key races in three states – Pennsylvania, Kentucky, and Arkansas. On election eve, here is the central question to each race.

One hurdle for a Supreme Court nominee is to get through the first week without creating a controversy. So far, Elena Kagan has negotiated the halls of Congress deftly – and quietly.
