Final answer:
Dual eligible beneficiaries account for 64% of all Medicaid spending, mainly directed towards the disabled and seniors, but the exact Medicare spending is not specified in the available information.
Step-by-step explanation:
Dual eligible beneficiaries, referring to those who qualify for both Medicaid and Medicare, account for a substantial portion of the spending for both programs. Specifically, dual eligibles make up 64% of all Medicaid spending, a significant figure that highlights the extent to which these groups rely on Medicaid. This spending is primarily directed towards those who are blind or have a disability (44%) and seniors (20%). Unfortunately, the specific percentage of Medicare spending for dual eligibles is not provided in the provided information, thus we cannot offer the exact answer in this context.
