Some even say that what is happening with job growth and part time work growth is what would have happened absent Obamacare.

Annual healthcare cost increases have also been the lowest theyve been in years. https://www.whitehouse.gov/sites/def...embargo_v2.pdf

It also, at the very least, has helped thousands of people with pre-existing conditions pay for those conditions.

Its also largely a congressional thing, not a potus thing. Yeah, Obama played a significant role, but the biggest role was congress. If you wanna take pot shots at Obama personally, attacking his policy on drone strikes shoulda been number1.
