In Texas, which hasn’t sent a Democrat to the U.S. Senate since 1988 and hasn’t had a Democratic governor since George W. Bush denied Ann Richards a second term in 1994, Republican candidates go to great lengths to burnish their conservative credentials-even if doing so means tying fellow members of the GOP to Democrats or, worse still, liberals. Case in point: Texas Lt. Governor David Dewhurst.

Late last month, Dewhurst-the leading Republican contender to replace retiring U.S. Senator Kay Bailey Hutchison-hurled the “liberal” epithet at the candidate he apparently feels is his toughest challenger, former state solicitor general and current Morgan, Lewis & Bockius appellate litigation partner Ted Cruz.
