The Politico is reporting that some moderate Senate Democrats who followed their party off the cliff on health care have become squeamish about taking risks the second time around with cap and trade.

“I am communicating that in every way I know how,” said Sen. Mary Landrieu (D-La.), one of at least a half-dozen Democrats who’ve told the White House or their own leaders that it’s time to jettison the centerpiece of their party’s plan to curb global warming…

“We need to deal with the phenomena of global warming, but I think it’s very difficult in the kind of economic circumstances we have right now,” said Indiana Democratic Sen. Evan Bayh, who called passage of any economywide cap and trade “unlikely…”

“I’d just as soon see that set aside until we work through the economy,” said Sen. Ben Nelson (D-Neb.). “What we don’t want to do is have anything get in the way of working to resolve the problems with the economy.”

We’ll see how many hold firm after the leadership offers them some pork and the president whispers some sweet nothings in their ears.
