Really? Reporters and politicians have searched for these mysterious slighted people who have had their premiums go up for the exact same plan. You should call the O'Reilley factor, you could be a star!
A lot of people could not buy crippled insurance plans with insanely high deductibles and severe limits on coverage, because those were outlawed by the plan. Also, some people were bumped from subsidized plans to fend on the open market, but that's shitty employers taking advantage of their employees, and not the fault of the ACA.
Finally, with the heavy subsidies to your premiums, the same plan usually cost less under the ACA. You could however talk about the cost of insurance in 5 years when the subsidies start to wear off, but, hey, I imagine the republican leadership has plenty of ideas to help the common folk with that.
