He may be slime, but because of the compromise that was done, R's had and have nothing. And have been completely embarrassed by it.
Other than hate for the ACA. dump complains that they have nothing, but nobody seems to point out that HE doesn't have any alternative, either. The only thing dump contributes is repeal and nothing- which is not what he sold is voters. Although, I expect that his voters anticipate that to come up someday. Not sure when...
(when reason would be- if you really have something that's a good replacement, you would have it on the table right away, and not just rely on R's for their (lack of) ideas.)
This R thinks single payer is the way forward. The stigma around it unfortunately will prevent it from happening for awhile yet.
