The very year ACA took effect my health plan was canceled, my doctor went off-network, my new plan had 3x the annual premium and has grown 30% year over year, as have deductibles, and I fight tooth and nail every single charge to make sure it is in network and covered.
Yes, one anecdote is not data. But there is no more validity to the politician's lie that I can "keep my health plan, keep my doctor, and health care costs will go down."
