PRI isn't looking too hot after this year's elections
Yeah, hard to see how they recover this time.
Especially that AMLO is basically the PRI but more committed to reform and economic leftism. Their getting squeezed by MORENA on the left, and now more centrist PAN coalition - since PRD is part of the pact.
But beyond this, I'm going to state the obvious that nobody has yet - the German SPD. Polls are basically placing the Union out ahead, and then all the other parties are fighting between 20 and 10 percent of the vote. The SPD is becoming a minor party for union members, far removed from its once national presence. Once Merkel leaves the Union, there will be a turning point. Either the SPD can capitalize on the opening and rise once again, or the new CDU leader will ride their honeymoon to more electoral victories.
