If the economy is still roaring at record low numbers (and no actual criminal scandal, or major war happens) then yes. Absolutely he'll win re-election.
For what it's worth, unemployment numbers are predicted to dip to 3.3% in 2019 and 2020....An absolutely phenomenal number that would seal his re-election.
It's impressive to have had two consecutive years of prosperity, but if that continues for another 2 years, it will be hard for Trump to be voted out of office after 4 years of the strongest economy in generations, especially when its juxtaposed with the 2008 financial crisis and the Obama years of stagnation.
People vote with their pocketbooks.
Tell that to Hiary when the same economy was roaring and she lost under an ethics cloud and Trump can be defeated with a 44% approval 😁
