Can I get Medicaid if I am 68yrs , retired , and work part time and have retirement income of $2000.00 per month,plus 100k bank account ???

No and I think you know very well that your income and resources makes you ineligible for Medicaid.  So what was the point of your even asking this question?  Are you confusing Medicaid (for poor people) with Medicare?  Medicare doesn't care about your resources and your monthly premium for Medicare is based upon your yearly income.

No. Medicaid is only for the destitute.

no.............................

No. But you are probably eligible for Medicare. (Your savings and retirement income can cover Medicare Part B)

No. Your income is well above poverty level, and you have assets. 

No.  Medicaid is for poor people.  $2000/mo. is not poor enough!

But over 65, you're entitled to Medicare.  Medicare is about the same thing as Medicaid, except it's for old people, not poor people.

Stop. Just stop. Go away and never return.
