A key bill on climate change may not make it through Congress this year.

Sen. Dick Durbin, D-Ill., tells Reuters passing the complex health care bill is the Democrat's first priority.

Other senators agree, saying they have enough on their plates this legislative session than to work on the climate bill.

Most Senate Republicans oppose the bill.

So Democrats would need nearly all 60 seats held by Democrats to line up behind the climate change legislation.

And some senators say for now, that may be one fight too many.
