Sen. George V. Voinovich (R-Ohio), a strong auto industry supporter, acknowledged that some of his colleagues simply did not want to help the UAW.
"We have many senators from right-to-work states, and I quite frankly think they have no use for labor," he said. "Labor usually supports very heavily Democrats and I think that some of the lack of enthusiasm for this [bailout] was that some of them didn't want to do anything for the United Auto Workers."
One major car dealer said conservatives let political ideology get in the way of protecting the country's interests.
"Being a Republican myself, I feel very betrayed by the Republican Party right now," said Beau Boeckmann, vice president of Galpin Motors Inc. in North Hills. Galpin has the nation's largest Ford dealership as well as lots where it sells eight other foreign and domestic brands.
The anti-union sentiment rose to the surface in the final desperate hours of negotiations. Republicans insisted that the UAW agree to cut its wages to be competitive with foreign companies such as Honda, Toyota and BMW by a set date.
UAW officials and their Democratic allies balked, saying the autoworkers were being told to make sacrifices that had not been demanded of other industries receiving government bailouts.
"We could not accept the effort by the Senate GOP caucus to single out workers and retirees for different treatment and to make them shoulder the entire burden of any restructuring," UAW President Ron Gettelfinger said, arguing the union had gone further than any other stakeholder in making concessions to help the companies avoid bankruptcy.
But DeMint argued that the unions had helped create Detroit's plight.
"It is no coincidence that the healthy automakers in the United States are located in 'right-to-work' states and are not unionized by the UAW," he said. "Right-to-work" states bar agreements between trade unions and employers making membership or payment of union dues or "fees" a condition of employment, either before or after hiring.
Rep. John D. Dingell (D-Mich.), a labor ally, said Friday that Republican senators who opposed the bailout might have "wanted to crush a longtime political rival, the United Auto Workers," without concern for the economic consequences.
Democrats lauded the UAW as a hero in the bailout process for agreeing to new concessions on top of major ones given in 2005 and 2007. House Speaker Nancy Pelosi (D-San Francisco) called the union "courageous" just before the House approved the bailout Wednesday.
