I'm fine with the Medicaid expansion portion of Obamacare.  It is up to the states and governors if they want to expand it.  I'm not fine with the individual mandate - aka forcing millennials to pay for the insurance of baby boomers.  Premium supports for the ACA don't go very high; someone who is making $45K as an individual doesn't receive any.  I can tell you that living on $45K in many metro areas doesn't go very far even before being required by law to purchase a $500+ product each month.  And the kicker is that the premiums are so high that most millennials will end up paying any healthcare costs out of pocket anyways.
