There were a lot people on the Obama band wagon early on including a lot of the Establishment Republicans.
So many of the GOP pundits voted for Obama including Peggy Noonan so Trump saying nice things about Obama is no real surprise.
A lot of people were saying “nice things” about Obama - they weren’t praising his policies like Trump - namely the stimulus that continues to be a drag on the economy to this very day. In addition, there are lot of things on this video Trump stated in this very campaign - not from the “past.”
Not included in this video is Trump literally attacking conservatives and what we stand for on the campaign trail - in this campaign. Is that also “from the past”?
