<p>A notorious bank fraud case provided more ammunition yesterday for shots fired between Lamar Alexander and Bob Clement in the U.S. Senate race.</p>
<p>In the latest round, the Clement campaign accused Alexander of taking $50,000 in campaign contributions raised by the late C.H. Butcher Jr. and later lobbying federal regulators to preserve the banking empire Butcher and his brother, Jake, had built. The Butchers went to prison for bank fraud after federal and state regulators padlocked their failing banks in 1983.</p>
