Only a minority of Americans are giving a thumbs up to the rollout of the Affordable Care Act health care exchanges, according to a trio of new national polls.

Just 12 percent of people questioned in a CBS News poll released Tuesday say they think the process is going well, with nearly half saying it's not going well and nearly four in 10 saying they can't evaluate the signup process at HealthCare.gov.

The state level online exchanges, which opened for business on Oct. 1, are intended to allow those without insurance to sign up for health care, and are a crucial part of the ACA.

Less than 3 in 10 surveyed in a Pew Research Center poll released on Monday say the online exchanges are working very well, with 46 percent saying they are not.

Besides the expected partisan divide, the poll also indicates a racial gap. Just 24 percent of white respondents, but 51 percent of black respondents say the exchanges are working well.

And the survey points to generational and income divides.

"Young people and those with annual household incomes of less than $30,000 are divided in their evaluations of the exchanges, while the assessments of older and more affluent Americans are more negative," says a release from Pew Research.

An ABC News/Washington Post poll suggests that major problems with the health care law's website may just be an appetizer.

Fifty-six percent of those questioned in the survey, which was released Monday, say the website failures are a sign of broader problems to come, with four in 10 saying they are an isolated incident.

More than eight in 10 Republicans see the website failures as part of a larger problem with the measure, while most Democrats describe it as an isolated incident.
