Watch the business page and you know why John Cornyn moved his July 13 fundraiser to a ranch owned by oilman/rancher Walter Mize. It was scheduled for the Beaumont Ranch, near Grandview (which is south of Fort Worth), but the owner of that spread is Cornyn supporter Ron Beaumont. Beaumont is also the chief operating officer of WorldCom. Revelations about that company's accounting scandals prompted Cornyn to start up the legal machinery in the attorney general's office–he's launched an investigation–and to move the fundraiser for his bid for U.S. Senate.
