Huge deficits for sure, but I don't think much of ACA will get repealed. Some tweaks, the repealing of the funding mechanism (read huge tax cuts for wealthy) and a re-branding. But they aren't going to cut health care for 20 million. The federal land and oil drilling can't change much in 4 years. If the American people don't want it, vote him out and 4 years and put a halt to it.
