Here are two different arguments to back up two different opinions. You can choose whichever you agree most with:
Yes, US states should have to listen to the president's legislation. States are united under federal US law and legislation. If states refuse to follow federal law, we are no longer united, and it's as if each state is a separate country.
No, US states should not have to listen to the president's legislation. The thing that makes the US the US is the power each individual state has. Each state has it's own individual needs that need to be accounted for, and every state cannot be accommodated under federal law.
