1 - Fix the debt situation or get us on a path for it to be clearly resolved. This will have to be multi-pronged: As Chris likes to point out, we will need to tax a bit more to do this, but we need to significantly reduce spend, as well. Neither will work alone.
2 - Get immigration and the border under sustainable control.
3 - Mend some fences. Let's argue and debate like it's the 80's and 90's, not these last couple of decades. Find roles in the government for some trustworthy, moderate democrats.
4 - Accelerate the path to nuclear energy.
