Arkansas is ripe for 'tea party' activism to grow and target incumbent Sen. Blanche Lincoln – and perhaps even GOP Senate candidate John Boozman – in the November election.
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 Arkansas primary on Tuesday is a test for the centrist stance of incumbent Sen. Blanche Lincoln, a Democrat. Runoffs may be needed in both the Democratic and Republican contests.
