In his first two years Barack Obama had a Democratic House and Senate (http://wiredpen.com/resources/political-commentary-and-analysis/a-visual-guide-balance-of-power-congress-presidency/)...and all he got done was ramming through a very flawed healthcare Bill (the ACA).
Likewise, from 2003 to 2007, G W Bush had a Republican House and Senate...and got little done. He did hang Sarbanes-Oxley a ham-handed response to the 2001 financial scandals (Enron, Tyco, Adelphia, Arthur Andersen, etc. which resulted in the vaunted "Jobless Recovery."
Now, Trump will have at least 2 years with both Houses of Congress in GOP hands. Unfortunately for him, the establishment GOP reviles Trump even more than most Democrats...and for better reasons.
Arizona and South Carolina SHOULD do the rest of the nation a favor and get rid of John McCain, who disgraced himself and his Party in the 2008 election and Lindsay Graham, respectively. THAT would be a nice start.
