Trump entered office on January 20, 2017, and starting with February 2017 he has been President for 29 months. Total job growth during that time has been 5.613 million or 194,000 per month with those results being helped by the tax cut.
Working back from January 2017, Obama’s last month in office, there had been 6.423 million jobs added or 221,000 per month. The difference for the 29 months is 810,000 more jobs or 27,000 more per month than Trump.
Note that back in January this year the total difference was only 194,000, which means over the past five months it has increased by 616,000. And looking at the next six months with Obama’s job numbers of 188,000 to 327,000 per month, the gap should only increase and cross 1 million.
