Political Ticker:

Six in 10 Americans support a “cap and trade” proposal to cut pollution, according to a new national poll.Sixty percent of those questioned in a CNN/Opinion Research Corporation survey say they favor “cap and trade,” a Democratic sponsored plan in which the federal government would limit the amount of greenhouse gases that companies could produce in their factories or power plants. Thirty-seven percent oppose the proposal, which would penalize companies that exceed greenhouse gas limits with fines or by making those businesses pay money to other companies that producer smaller amounts of pollution.

The support was especially strong among everyone except Republicans and people over 50 years old:

The survey indicates a generational divide, with 68 percent of Americans under age 50 supporting “cap and trade” but those 50 and older split on the issue.

“This is one more example of the growing generation gap that is shaping politics and policy in this country,” says CNN Polling Director Keating Holland. “Younger Americans voted for Obama and tend to welcome change. Older Americans were less enamored of change in the 2008 election and senior citizens were the only age group that voted for John McCain.”

The poll also suggests a partisan divide, with three in four Democrats backing the proposal and nearly six in 10 independents on board as well, but only four in 10 Republicans supporting “cap and trade.”

“The support of independents will be crucial to any cap and trade proposal,” Holland says. “Independents may not be red or blue, but they appear to be green. Earlier polls indicate that Independents believe in global warming and believe that the government can take steps to curtail the problem. But the environment is not a big priority for Independents, as it is with Democrats.”
