Now, Saperstein said Obama has been a "gigantic disappointment and the weakest president in my lifetime of either party."
Other groups also expressed their disappointment at the tax cuts.
Lee Farris, estate tax policy coordinator for the organizationUnited for a Fair Economy, said the tax proposal was "outrageous."
"The deal would make the estate tax even weaker than it was under President Bush, the weakest it's been in more than seven decades," said Farris, whose organization is comprised of business owners and farmers across the country.
Farris said the deal was "unacceptable" because it "gives away too much and gets too little in return," via the extension of unemployment benefits and low-income tax credits.
"The people who already have the most money have said, 'We're going to have a weaker estate tax or you can forget about unemployment.' And to me, that's an immoral position," said Farris. "They're saying that's more important than [helping] someone who has lost their job through no fault of their own."
Dave Eiffert, a small business owner who has worked with United for a Fair Economy, said he hoped for a higher estate tax ceiling and deeper tax cuts for the middle class instead of tax cuts for those making $200,000 and more.
Eiffert, co-owner of Snoqualmie Brewery in Snoqualmie, Wash., said he is below the $200,000 income level and is opposed to the notion that tax cuts to the wealthiest will trickle down to create jobs for others.
But Eiffert said it is not too late for the public to speak its mind on the various tax issues before the year comes to a close.
"I always hold out hope until it is a done deal," said Eiffert. "I urge people to contact their legislators and tell them what they want done. And I hope there will be something better than what has been proposed."
