How far back can Trump turn the clock?

It is going to be interesting to see how much President Donald Trump will be able to or even try to get done.

In his first 100 days, he promised, he will cancel “every unconstitutional executive action, memorandum, and order issued by President [Barack] Obama," which he will have the power to do. These could include the Syrian refugee program; increased regulations on greenhouse gas emissions for the nation’s power plants; the right to take family medical leave for same-sex couples; and halting the deportations of illegal immigrant children. And he vowed to repeal Obamacare, which would strip over 20 million Americans of their health insurance, although this may be more difficult than he imagines: the insurance hogs will not go easy from the trough.

He threatened to impose a 45 percent tariff on Chinese imports, officially branding China as “a currency manipulator,” while also seeking a 35 percent tariff on Mexican imports, but pressure from the business community should be enough to keep him from setting off a trade war and sparking a world-wide depression (the stock market already seems to be pricing in tax-cut Trump but ignoring trade-war Trump).

He promised to deport 2 million “criminal illegal immigrants” on his first day in office, but it took Obama six years to accomplish that, so expect a slow acceleration there, and the wall is a non-starter.

More seriously, he pledged to cut all federal funding to “sanctuary cities,” which are municipalities whose local policies do not permit prosecuting people only for being undocumented. He said he will cut all payments to U.N. climate-change programs which, in addition to likely signaling an increase in U.S. emissions, will also cut budgets of U.S. universities and laboratories dedicated to studying climate-change. Some of this is real. Some of it is campaign rhetoric. More dangerous may be that he won't veto actions by the whackos controlling Congress.

Also, amid all the whining and puling about Trump, it's important to remember that Obama still has a month and a half to try to ram through TPP.

Time to get organized, folks.
