How the GOP sabotaged Obamacare

You're heard their BS lies about Obamacare failing. The main reason prices have gone up and some providers are pulling out is because of GOP sabotage. Obamacare had built-in risk corridors, which meant that the money insurance companies lost in the first 10 years of the program due to taking on people with pre-existing conditions would be remunerated. But in '15 Senator Rubio and his cohorts injected a poison pill into a spending bill that eliminated the risk corridors, thereby withholding $2.5 billion to insurance companies that year. That is why some companies pulled out and others raised rates. So why aren't Democrats shouting it out to everyone?
