While support for Democrats' health care plan, which passed a year ago along party lines, remains the same, Americans haven't warmed up quite yet to the Republican plan, either.
In an ABC News poll released this week, 65 percent of Americans said they opposed changing Medicare to a system in which the government would give older Americans vouchers with which to buy private insurance.
The Republican budget plan includes what's been widely described in news reports as a voucher or voucher-style system, though Ryan has maintained that it's not a voucher system because subsidies would go directly to insurance companies.
Ryan's plan has little support in the Senate, which is controlled by Democrats, and has been panned by President Obama as being "fairly radical."
The Democrats' health care plan isn't faring any better. A year after it was passed, Americans remain confused about what it entails. In Kaiser's March health tracking poll, 52 percent of those polled said they did not have enough information about the health reform law to understand how it would affect them personally. The poll found that 42 percent of Americans hold favorable views of the law, while 46 percent view it unfavorably.
