Governor's Mercury Mariner Hybrid what is its FE at 90 mph?
SANTA FE - Few have shared a laugh about Gov. Bill Richardson's apparent penchant for speed since a reporter rode along with him in April and wrote that his hybrid SUV was going upward of 90 mph.
At least until the debut this week of a state Republican Party bumper sticker that reads: "I'm not speeding, I'm with the governor's security."
There's been steady interest in the sticker since the party announced it Tuesday, said spokesman Jonah Cohen. The sticker is tied to the unveiling of a new party Web site, N.M. for sale
Richardson's office has denied the governor was speeding earlier this year.
Albuquerque police in June of 2005 tried to pull over Richardson's SUV after its speed caught an officer's attention. The State Police officers who were driving Richardson didn't recognize the APD vehicle because it was unmarked, and didn't pull over.
And in September of 2003, a Washington Post reporter chronicled a ride with Richardson in which he hit speeds of 100 mph. Security issues were involved, according to the Governor's Office.
Gilbert Gallegos, a Richardson spokesman, said he's hoping another bumper sticker will be printed.
"I'm waiting for the, `I'm not a socialist, I'm a teacher' bumper sticker. There are 22,000 potential voters around the state who might be interested in that sticker," he said.
The statement is a dig at Republican gubernatorial candidate John Dendahl, who earlier this year said he thinks "most teachers in schools are of a socialist inclination."
