Kaiser Health News...

...has a new poll out that is very revealing (my emphasis):

22 percent of Americans incorrectly believe [the Affordable Care Act] has been repealed and another 26 percent are unsure or unwilling to say.

...Only 52 percent of Americans accurately said the health care law, which passed last year, remained intact, according to the poll from the Kaiser Family Foundation.

Nearly one in three Republicans thought the law had been repealed.
___

The poll found that unfavorable views of the law among the elderly have risen to 59 percent, up from 40 percent in December.

This is interesting, considering that the law barely affects the elderly; they already have Medicare.

There remains no consensus about whether to keep, expand, replace or repeal the law. Forty-eight percent are opposed to the law, while 43 percent favor it. Sixty-one percent of those polled oppose Congress cutting off funding of the law in order to block it, as many Republican lawmakers are considering.
___ 

19 percent of voters want to repeal the law and replace it with a Republican alternative.

There is no Republican alternative.
