According to documents obtained by the Barr campaign, neither John McCain nor Barack Obama complied with Texas Election Code § 192.031, which requires that filings must be submitted “before 5 p.m. of the 70th day before presidential Election Day,” listing the “names of the party’s nominees for president and vice-president.”

“The Election Code of the State of Texas imposes requirements on a political party, which must be met if its candidates for president and vice-presidents are to appear on the general election ballot,” Russell Verney, Bob Barr’s campaign manager stated in a letter sent to the Texas Secretary of State’s office. “The Democratic Party and Mr. Obama, and the Republican Party and Mr. McCain, blatantly ignored the Texas statutory deadline.”

I’ve got to go with Bob Barr on this one folks.  The rules are the rules, and the major-party candidates aren’t exempt from them.
