I disagree with your assessment. The economy grew under Obama, but for the most part it sputtered. Unemployment in that time span was unacceptable, but Obama told us to get used to it, that’s the new normal. Business was absolutely strangled with new regulations, more government interference in the economy. Any competent economist will tell you that any - any! - government interference in the economy will have a negative effect on growth and prosperity. The more interference the greater the negative effect.
Taxes were stifling on individuals and businesses alike. Tax reform is totally a Republican achievement. Did a single Democrat vote for tax reform, lowering taxes?
For all his bufoonerishness (is that a word?) Trump (and the Republicans) deserve accolades for improving the economy. The Democrats have looked foolish with their nonstop antiTrump rhetoric.
I recognize some weaknesses in the enactment of the Republican agenda. I also recognize the party of the sitting President usually loses seats in the midterm elections. Trump’s approval ratings are lower than they deserve to be. The Democrats have several things going for them in the elections, you have legitimately pointed them out. Republicans should be concerned.
But if the Democrats attempt to take credit for the incredible expansion of the economy they will be laughed out of the room.
Obama took office during the worst financial crisis since the Great Depression. When he took office, the unemployment rate was 7.8%. It would peak at 10.0% nine months after Obama took office. When Obama left office in January 2017, the unemployment rate was 4.8%. This was below the historical norm (dating back to 1949), which is 5.6%.
From January 2009 through January 2017, the jobless rate dropped 3%. Since 1949, the U.S. only saw a rate drop greater than this under Clinton and the Kennedy/Johnson administrations. And again, this was done after inheriting a horrible financial situation. The economy added 11.6 million jobs under Obama.
Do you really want to claim that a 4.8% unemployment rate is unacceptable compared to 7.8% or 10%? Do you really want to claim that the addition of 11.6 million jobs after inheriting a dire financial situation is unacceptable?
There are other numbers that can be pointed to as well. Aveage weekly earnings and incomes increased for Americans under Obama. These numbers must also be seen within the context of what was inherited. For example, when Obama took office, the inflation-adjusted income for Americans had dropped 4.2% in the prior eight years. When Obama left office, there had been a 5.3% gain.
On top of this, after-tax corporate profits inceased under Obama. The S&P 500 index rose 166%. Over 15 million Americans received health care. And so forth.
Since January 2017, this positive trend has continued. For example, four months after Obama had left office, when Trump had done very little in terms of economic policies, the unemployment rate was at 4.3%.
Now, I realize that it is hard for some to give Obama credit for anything. And politics is politics. But the facts are the facts.
I don't disagree that Trump can attempt politically to claim credit for the continued growth, citing to confidence, and his tax/regulatory policies. However, Democrats can also remind Americans that we still have yet to see the long-term impact that these policies are going to have. There is absolutely no reason why the Democrats should or will cede the economic issue to Republicans.
