Trump is bound to "veer left" because his promises are so far to the right, he can't (and never could) possibly keep them.

The Wall won't be a 10-12 ft. concrete barrier stretching the entire length of the Mexican boarder. (In fact, he will probably add only a few hundred miles of fencing to what already exists.) Illegal immigration, as measured by authoritative sources will be higher by the end of the next term than it is currently. Breitbart (or equivalent) will publish their own bogus numbers, which Trump will cite.
He won't deport the entire 11 million illegal immigrants in this country. He'll probably deport less than half of them, if that, and then declare victory. And, after an initial push that will last for a few months, he will pull back any actions against employers hiring illegal immigrants.
He will toss out the TPP, but he won't make a "better deal" and we will end up in a worse situation (probably without an agreement).
We will come to the brink of a trade war with China and maybe some other nations, but he'll back off at the last minute, and most economists will agree that we are worse off as a result. He will, however, declare that we are much better off, and Fox and Brietbart will agree. Inflation will increase, while production will decline.
He will cut taxes, but most of the cuts will go to the top 5% or less. Many in the middle and lower classes will actually pay more in taxes. The deficit will increase.
He will get a Transportation Works bill through Congress, since Obama won't get credit for it anymore.

But the bill won't be paid for, and the deficit will increase.
He will move back civil rights for gays and minorities, and expand libel laws, until the Supreme Court finds his actions illegal. He will declare the Supreme Court biased and rigged, and may not respect one or more of the rulings, which would lead to a Constitutional crisis.
He will, of course, repeal Obamacare. After a few months, he will sign a new health care law, which he will say is better than the ACA. Millions of people who have health insurance now will no longer have it with the new plan. And the new plan will not be sustainable, since it still has the clauses to allow people to join with pre-existing conditions. After a few years, he will remove that clause, if the plan was not replaced by a single-payer system. Premiums will be much higher than they are now.
We will have more terrorist attacks than we did during the Obama Administration. Trump will use them to give the government more power and to limit more rights, mainly for minorities. The Presidency will be more powerful than it was with Obama.
And heaven help us if there is a major terrorist attack on the order of 9/11. Because he will ask from Congress sweeping powers, and he will get most of them. This would be in line with creating a fascist state, such as the way the Riechstag fire was used. (I sincerely hope I am wrong about this--but remember, you heard it here first!

)
The EPA will be eliminated or severely hobbled. Overall air and water quality will be worse as a result.
So while many things that the Right wants--Obamacare repealed, the EPA hobbled, taxes cut, gays and minorities not having more rights than whites--will happen, many things the Right doesn't want--more government, a worse economy, a higher deficit, fewer rights--will also occur as a result of the things that Trump will do.
The Right, of course, will blame all the bad things on the Left.
