The Wall Street Journal reports:
trucking companies say an 18-wheeler tractor configured to burn natural gas can cost about $200,000, roughly twice as much as a diesel version. And the trucks need special natural-gas fueling stations. The bill at the center of the tussle would provide tax breaks of up to $64,000 per natural-gas truck to transport companies and up to $100,000 per fueling station for owners of the stations. The tax breaks would end after five years. As of Tuesday, 185 House lawmakers, including 104 Democrats and 81 Republicans, were sponsoring the bill.
There are actually a surprising number of issues in Washington that don't break down on party lines. Or, to put it another way, bipartisanship can come pretty easily when it's about dispensing money via the tax code to an interested group.
