Obama Flip-Flops Again!

From the AP:

Democratic presidential candidate Barack Obama said Friday he would be willing to support limited additional offshore oil drilling if that's what it takes to enact a comprehensive policy to foster fuel-efficient autos and develop alternate energy sources.

Shifting from his previous opposition to expanded offshore drilling, the Illinois senator told a Florida newspaper he could get behind a compromise with Republicans and oil companies to prevent gridlock over energy.

Are there any issues left where this guy hasn't changed his position?
