Can you speak to a specific lie? Please, cite the exact wording. I have research the allegations that Vance lied, but so far have found no examples. Instead, I have found examples of insinuation that he lied.
Using the ACA as an example, Vance said Trump "saved" the ACA. And he did. He did not say Trump like or endorsed the ACA, but simply that he saved it.
By removing the mandate, Trump eliminated objections to it that would have ended it and that allowed it to "survive".
By removing the mandates, the insurance exchanges became nothing more than "a choice" for individuals and small groups to secure health insurance. Individuals were no longer forced to purchase uncompetitive health insurance. This meant that either the states and/or the federal government subsidize the exchanges, or they would fail. The states and federal government did subsidize them, since individuals and small employers were no longer forced to buy health insurance like I was for my family of four at $3400/month.
Having been a senior executive for Blue Cross and one of the nation's largest government health care program administrators, one could easily see that the ACA was designed to blow up in 2018 (which I wrote about before it was passed). Some experts believed Obama designed the ACA to force the country to adopt a single payer system when the exchanges collapsed. But Trump's actions and the subsequent decisions by states and the federal government to subsidize them have kept them alive.
I understand how people who have not worked at the highest levels of private health insurance and government health care programs might not have understood what was going on, but that does not change the fact, that Trump "saved" the exchanges. As an aside, I supported the Medicaid expansion component of the ACA and opposed the individual and small business exchanges specifically because of the flawed funding design.
That design is already costing taxpayers $100 billion annually. At some point, the exchanges need to be fixed with an assessment either on all health care expenditures (it would feel like a sales tax) or an assessment on health insurance premiums and "premium equivalents" (several states levy a premium tax to help fund health care costs for the poor).
What troubles me has been the poor reporting on the debate, which could help clarify the issues, rather than attempts to declare complicate and sometimes overly simplified responses given when you have 1 minute to respond to be lies.
Walz as an example has repeatedly denied he signed a bill that allows abortion up to the moment prior to a woman delivering a baby. But in fact, he did. But again, the devil is in the details. Now Walz says he favors restoring Roe v Wade, great, but that does not change the law as it exists today in Minnesota and if he thinks he made a mistake signing that bill, he should as governor push to have the state legislature revise it to conform with Roe v Wade.
We know Walz lied on about his time in China.
