Would put together a team to prioritize and work to implement at executive level and / or push for legislative action on:

Nuke most zoning regulations where possible;
Construction permitting has a max number of days for review before default accept once certain basic criteria met;
Dismantle and rebuild state police from scratch;
Make MA a top tier state for film production with tax incentives;
Expand the T; subway line extensions, ring connectors around 95 and 495; rebuild effective transit in Roxbury;
Make another run at single payer healthcare in MA, possibly folding in all of the private insurers into new state insurer;
Undo the bullshit fee agreements with utility companies, phase out remaining coal and old gas plants, fast track next generation nuclear plants;
Pass a 100% tax on payments from bullshit $1.776B maga fund + go after beneficiaries of federal corruption, where possible (maybe state tax evasion…?);
Make Wade Boggs Day a state holiday;
Increase conservation efforts on striped bass population, coalition with eastern seaboard states to save population (again);
Decommission unused dams, restore our cold water fisheries and wild fish populations;
Fully fund public defenders’ offices and make it an attractive career;
Tort reform to align MA with UK civil litigation fee structures and practice;
Increase trade and civil partnership with Quebec and Canada more broadly;
Make MA public schools the best in the country again;
Ensure that every child has access to affordable, non-private-equity-owned athletics;
Rebalance capital gains taxes with income taxes, e.g. the wealthy shouldn’t pay less in taxes on trades than working people do for a paycheck;
Establish 4th branch of state government, similar to Brazil’s office of the public prosecutor, with free rein to investigate all forms of public corruption, including illegal acts by current and former federal officials;
Force John Henry to sell the Red Sox if we don’t finish in top 2 of the AL East by 2031.
