Looks like Smokey Joe Barton's Gravy Train got an appropriate sendoff.

About 50 people showed up at the train station Friday afternoon to protest U.S. Rep. Joe Barton's weekend campaign fund-raising trip to San Antonio for supporters on a chartered train.

Holding a sign that read, "All Aboard the Gravy Train," Anna Brosovic said she was concerned because Barton, the chairman of the House Energy and Commerce Committee, seemed to be surrounding himself only with the wealthy and influential.

"Joe Barton's little trip epitomizes the culture of corruption that has taken over the Republican Party since they swept into power," said Brosovic, of Arlington, a Democrat who lives in Barton's district. "It's democracy for sale."

Iraq war veteran and college professor David T. Harris, the Democrat running against Barton in November for congressional District 6, said the trip was in poor taste in light of the federal bribery investigation stemming from the work of disgraced lobbyist Jack Abramoff.

"I don't think there's anything underhanded, but it's bad timing," Harris said.
