"Obama was the worst, and polls have shown it."
Which polls? Who was polled? Historians generally consider Obama an OK president - not great, not awful. Certainly not the worst. In fact, most of them rate Trump as the worst.
"Obama let the country's health care go to hell."
Wiithout the ACA ("Obamacare") I wouldn't have been able to get a health insurance plan for myself (during the 3-month waiting period) when I changed jobs. With my health history - as a 3-time cancer survivor - I would have been uninsurable. The ACA saved my ass.
"I have lost friends who were kicked off state insurance, simply because they lived one-inch out of the restricted area."
What is "state insurance"? I know of no rule in the ACA which designates "restricted areas" for medical insurance.
"Eight years with Obama caused this mess, now Trump is trying hard to fix it."
If you're referring to medical insurance or health care, Trump hasn't done *one thing* to fix it. Not one thing. I'd love to hear even one example - a verifiable fact - of something Trump has done to fix healthcare or health insurance, for the poor or middle class.
If you're referring to the economy, Obama inherited (from George Bush) the worst economy since the 1929 crash and by the end of his 2 terms, the economy had bounced back and it was rolling along quite nicely. Trump's getting the benefit of that, but he certainly isn't responsible for starting the recovery. My IRA lost $16,000 in the last quarter of 2018. My investments haven't lost that much since the last time we had a Republican in the WH.
