It also feels that Trumpism isn't a long lasting ideology and I tend to agree.
More ever, I disagree with this analysis. Jackson continued the Jefferson - inaugurated majority, McKinley the Lincoln industrial economy, and Roosevelt was a realigning President. Reagan's coalition has clearly lasted and shaped the presidencies and Congresses of his successors.
You might want to consider 2008-2016 as a dealigning era, where we move away from the Reagan Republican era and no party holds the majority stakes.
I think that 2016 is certainly the beginning of a realignment ... towards the Democrats.
EDIT: Let me elaborate a bit. The Lincoln Industrial realignment had the North and industrial labor and business behind it, and they were growing. The New Dealers had the working class behind it, which was hugely behind FDR. Reagan had the growing suburban majority. What's the Trump realigning group?
