According to the GOP sources, Senate Minority Leader Mitch McConnell, R-Kentucky, wants a “smaller, narrower” bill, which primarily includes tax cuts as well as some housing relief.
There is another group — including some conservatives like Sen. John McCain, R-Arizona, and some moderates like Susan Collins, R-Maine — working to craft a larger package that would include more of the infrastructure spending the president and Democrats are supporting.
But generally, the GOP sources say, the party is looking for more concessions from President Obama on spending.
The fact that the House Republicans were unified in their opposition to the plan — and that some fiscal conservative Democrats voted against it — also puts pressure on GOP Senate moderates to tow the party line. In addition, polls indicate constituents are mixed in their support for the stimulus package.
“We want it to be bipartisan and effective,” says Collins, a target of White House lobbying, who spoke at length with Vice President Biden, Budget Director Peter Orzag and Obama Economic adviser Larry Summers early on in the process.
“My constituents don’t want a huge, expensive package that doesn’t do the job.“ Collins also said. “The president needs to hold the line and Republicans need to make a good faith effort [to get something done.]"
