WASHINGTON — Republicans in the Senate appear likely to kill legislation to provide continued unemployment checks to millions of people and provide states with billions of dollars to avert layoffs.

It would be a bitter defeat for President Barack Obama and Capitol Hill Democrats, who have been trying to advance the measure for months as an insurance policy against a double-dip recession.

Despite another round of cuts to the measure aimed at pacifying GOP deficit concerns, the measure seems doomed to die by a filibuster.

Majority Leader Harry Reid, D-Nev., said he would pull the measure from the floor if Democrats lose the vote. Democrats hope political pressure from voters and business groups might eventually revive the measure.

The latest version of the measure contains a variety of provisions sought by lawmakers in both parties, blending jobless aid averaging about $300 a week with the renewal of dozens of tax cuts sought by business groups and a host of other legislation. It is considerably smaller than a version that passed with GOP help just three months ago.

"It adds new taxes and over $30 billion to an already staggering $13 trillion dollar national debt," said Minority Leader Mitch McConnell, R-Ky.

The catchall measure also includes $16 billion for state governments to avert layoffs, farm disaster aid, $1 billion for a youth summer jobs initiative and an extension of a bond program that subsidizes interest costs for state and local infrastructure projects. It would levy a new tax on investment fund managers but extend tax breaks such as lucrative credits that help businesses finance research and develop new products, and a sales tax deduction that mainly helps people in states without income taxes.
