Los Angeles Times: Leading voices in the Senate are considering a new tax on gasoline as part of an effort to win Republican and oil industry support for the energy and climate bill now idling in Congress. The tax, which according to early estimates would be in the range of 15 cents a gallon, was conceived with the input of several oil companies, including Shell, BP and ConocoPhillips, and is being championed by Republican Sen. Lindsey Graham of South Carolina.
