The 2016 US presidential election as analogous to the 2000 Mexican presidential election:
- The Democratic and Republican parties are merely two wings of the PRI.
- Trump and his supporters are the Alianza por el Cambio.
One obvious difference here is that Trump isn't defeating the Republicans and the Democrats in one swell foop. He defeated the Republicans first (in their own primary elections) and will now attempt to defeat the Democrats (in the general election).
But I think the dynamic is at least facially similar.
