I read the news about Trump going to Detroit to talk to the UAW strikers and how they don't want him there.

They seem to have forgotten about how Obama called the UAW workers "greedy" and how he wanted to tax their greedy "Cadillac" health care plans.

That did not happen because Trump got rid of the "Cadillac" tax.

I remember how Trump said he was going to repeal and replace Obamacare.  Trump did nothing for me but he got rid of Obamas "greedy" tax on the UAW health care so I guess they were looking forward to paying it and are angry at Trump for getting rid of it.

What's to stop Biden from putting the "greedy" "Cadillac" tax back on union health care plans?

If he gets re elected then there is nothing stopping him because he does not have to worry about running again.
