A Senate push for new gun control measures is in deep trouble. Growing numbers of Republicans are opposing it, which could spell defeat.
A first vote is expected Wednesday, focusing on background checks. The Senate planned to hold eight other votes as well, all of them amendments to a broad gun control measure.
They included Democratic proposals to ban assault weapons and high-capacity ammunition magazines. A GOP substitute for the overall gun measure may also be considered.
It all comes as a new poll shows support for tighter gun control has dropped significantly.
The new Associated Press-GfK poll found that in January, 58 percent of Americans supported the move in the wake of the Sandy Hook Elementary School shooting in Newtown, Conn. Now just 49 percent support the idea.
Also, more than half the public, 52 percent, expressed disapproval of how President Obama has handled the gun debate.
