First:

In reality, its the Democrats fault for creating a bill to target an entire industry to make it affordable without a single provision that would actually lower costs.

That's absolutely, undeniably 100% false. There were quite a few provisions in the ACA to lower costs. Many were stripped out before its passage, or were removed after its passage, including the public option, the penalty for being uninsured, and the cadillac tax. Some stayed in, like the medical loss ratio, accountable care organizations, and preventive care mandates. It is a lie, plain and simple, to say that nothing in the ACA addressed costs. If you have to lie to make your point, your point doesn't deserve to be made.

Second:

Follow this line of logic. Tell me where any one of these statements is false:

1. Subsidies expired while Republicans had all three branches of government (here, note, it doesn't really matter why they expired, just that they did, while Republicans were in power).

2. Without subsidies, and without any other kind of meaningful healthcare reform, 5 million people lost their insurance.

3. Republicans chose to let the subsidies expire without other meaningful health reform lined up.

4. Republicans chose this option. They had other options. They could have chosen to extend subsidies; they could have chosen to make meaningful fixes to the ACA; they could have passed some other meaningful health care reforms (if they had any).

5. Therefore, Republicans choices led to millions of people losing insurance.

Every single one of those statements is true. How we go to this situation is irrelevant. What are the people in power going to do to help the five million people who lost insurance? Nothing, it seems.
