I would say pull the knives out American zero has stabbed in which are bleeding most profusely first and suture.
Defund zerocare - especially the 30hr work week monstrosity.
Take Amnesty off the table.
Repatriate American businesses.
Build the pipeline.
Get the economy running on all eight first.
I'd like to see them, for the first step, explicitly defund Obamacare spending that is not authorized under the letter of the law. In particular, that would defund subsidies for states without a state exchange, killing most of ObamaCare by demanding that the stupid law be implemented as passed.
Second, they should at least keep the potential for amnesty on the table: pass a real border security bill with a promise that they will take up additional border topics if and only if the borders are effectively secured to prevent more illegals from crossing. The second topic would be enforcement of laws against hiring illegals, followed by fixing the legal immigration system. After that, we could look at what to do about illegals who have been here a while - my guess is that the best option to offer would be for them to go home and apply for legal entry. Why give criminals an advantage over those who follow the law? So Amnesty wouldn't be "off the table", we just wouldn't move forward on it at least until the borders are secure and laws are being enforced.
American business is a big one. Repealing anti-business laws is the key path to bringing business back. Those would be a very good start.
