Five days ago, Donald J. Trump posted a message on Twitter that proclaimed for the umpteenth time that his poll numbers are “better” than those posted by former President Obama.

He wrote: Presidential Approval numbers are very good – strong economy, military and just about everything else. Better numbers than Obama at this point, by far. We are winning on just about every front and for that reason there will not be a Blue Wave, but there might be a Red Wave!

The raw polling data can be disputed. However, I feel the need to look briefly at the comparative moments in time of both men’s presidencies.

Barack Obama took office on Jan. 20, 2009 while the nation’s economy was in free fall. Banks were closing. Investment firms were collapsing. People were losing their jobs by the thousands daily.

By August 2010, the economy had not yet made the turn, but it was starting to show signs of life. It got so good that Obama was re-elected in 2012 and the jobless rate continued to decline right up until the end of his presidency.

Enter Donald Trump, who took the oath on Jan. 20, 2017. The economy was in far better shape than it was when his immediate predecessor took office.

I give the president credit for the great job numbers that have accrued since he took office. But it’s good to understand that he started with a much higher benchmark than the one Obama inherited eight years earlier.

I just hope that Trump’s damaging trade wars with the EU, China, Canada and Mexico don’t undo much of the good that has occurred. I fear there the damage is beginning to stretch our economy at the seams.
