Also relatively unchanged over the last three weeks is the wide concern over the potential economic fallout. There remains a broad expectation that a lack of agreement will deliver a "major effect" on the economy.
What has changed since the previous poll is that more people are paying attention to the policy battle - two-thirds are following the debate closely - but that has not led to a better-informed public. Only 28 percent say they understand "very well" the consequences of missing the deadline, about the same as the 26 percent saying so in the prior survey.
Obama has called for raising tax rates for the wealthy, while congressional Republicans have urged that Bush-era tax cuts be extended for all taxpayers. Numerous polls have shown that raising taxes for high-income households is popular, and that is perhaps the reason that Americans seem inclined to blame the GOP if there is no deal.
Fully six in 10 voters in November supported raising tax rates on income exceeding $250,000, a key Obama campaign position, according to a Fox News exit poll. After the election, House Speaker John A. Boehner (R., Ohio) signaled an openness to raising revenue from the wealthy by limiting tax deductions, but Republicans have refused to budge on higher tax rates.
