Cruz, meanwhile, attacks Dewhurst as a "timid, moderate politician" who too often has compromised with Democrats.
"Enough of these little kitty cats we keep sending to Washington," Cruz said. "David Dewhurst will compromise every day in the U.S. Senate. ... It's what he's done every day in state government."
Boasting about his experience as a top business executive, Leppert calls Dewhurst a career politician and Cruz a government staffer. Dewhurst says Leppert's record as Dallas mayor is too liberal for Texas Republicans.
Whoever wins the GOP nomination will face one of two Democrats, former state Rep. Paul Sadler and party activist Sean Hubbard. No Democrat has won a statewide office in Texas since 1994.
