Trump's first 100 days
Trump should move quickly with the Republican Congress to implement the major points of his agenda.
One: The House must pass a bill to repeal Obamacare, send it to the Senate, and then send it to Trump for his signature. After repeal, Trump can submit his proposal for health insurance, to allow consumers to select the type of coverage they want. For example, you can choose what coverage you want for your auto and home, the deductibles, the items covered, and the extent of insurance. Similarly, for health insurance, you should be able to choose what medical care you want, such as rejecting maternal care, chiropractic care, physical and mental therapy, and others that may not be appropriate for you.
Second, Trump should send his tax reform bill to reduce tax rates for individuals and corporations.
Third, Trump should announce his nominee to replace Justice Scalia on the Supreme Court.
These are important and require immediate attention by Congress. Congress is usually more agreeable during the first few months of a presidency, and Trump must seize the moment to move the health insurance and tax legislation and the Supreme Court nominee.
The other aspects of his agenda Trump can achieve by agency regulations and executive orders. He can rescind the Iran nuclear deal and tell Iran we start negotiations anew. He can rescind many of the Obama executive orders he disagrees with. He can immediately order the IRS and the Justice Department to stop the lawsuits with the Little Sisters of the Poor over providing contraception and abortion coverage.
Trump should start construction of the border wall, with electronic monitoring, as soon as possible; order enforcement of our immigration laws to deport illegals who have committed crimes and overstayed their visas; and stop federal aid to "sanctuary cities."
There is then the issue of the investigation of Hillary Clinton. Obama will probably pardon her for all crimes she committed or may have committed regarding the emails. He may not pardon her for the Clinton Foundation. If Obama does not pardon, then there may be pressure on Trump to appoint a special prosecutor.
Trump should move on the tax reform and Obamacare repeal and Supreme Court nominee before he deals with a special prosecutor. Obama could do Trump a favor by pardoning Hillary, because it would remove this issue from Trump, and the blame would be on Obama and Hillary.
It appears that Hillary will be very friendly and "bipartisan" to dissuade Trump from appointing a special prosecutor if Obama does not pardon her.
In summary, Trump should focus during the first 100 days on the important long-term issues of repealing Obamacare, reducing tax rates, appointing a Supreme Court justice, and then dealing with illegal immigration and the free trade issues.
