Democrat platform "lacks the 2008 version’s explicit call for cap-and-trade"; also no longer pledges to free the nation from the "tyranny" of oil

Dems back global climate deal in platform - The Hill's E2-Wire

CHARLOTTE, N.C. – The Democrats’ official platform expected to be approved at the party's national convention on Tuesday calls for an international deal to limit greenhouse gas emissions.
...
Domestically, the platform is weaker in calling for climate change legislation that the party's previous platform in 2008.

It lacks the 2008 version’s explicit call for cap-and-trade, a proposal that collapsed in the Senate in 2010 after House Democrats moved legislation through the lower chamber. Some Democrats say that vote was a factor in Democrats' losing their House majority in the fall of 2010.
...
It supports an “all-of-the-above approach to developing America’s many energy resources, including wind, solar, biofuels, geothermal, hydropower, nuclear, oil, clean coal, and natural gas.”

The 2008 version lacked this language, and indeed made multiple pledges to free the nation “tyranny” of oil – a line that’s not repeated in the 2012 version.
