That's excellent! What happened during or just before the Suarez Chancellorship to enable, and make necessary, an indepdent Chancellor and a technocratic cabinet and referendums? On what were those referendums? And how is the Suarez Chancellorship viewed among the populace?
Also, does this USA rule all of OTL USA? Or less, or is it even more territory?
The 2005 election result was inconclusive, with Congress split between a number of conflicting blocs, with no workable majority possible. Labor managed to cobble together just enough support to govern, but this collapsed very quickly. By the time Kaufman resigned, it was clear the continuation of the Labor minority government was not possible. New Chancellor Hussain talked several times with President Carpenter in the days after taking office, ultimately agreeing to step aside in favor of Dominic Suarez, an experienced lawyer and diplomat, who would become interim Chancellor with the intention of trying to build a new coalition or, if that was not possible, call new elections. When Plan A failed, Carpenter opted against Plan B, expecting a second election to deliver a similarly messy result.
Suarez was at this point quite popular, and was able to garner enough Congressional support to lead a non-partisan, technocratic cabinet, intended only to last until the political situation could be worked out - which ended up stretching to over two years, during which time his popularity eroded away. Ultimately, the government arranged a number of referendums aimed at preventing a repeat of this situation. These included proposing the prohibition of non-parliamentarians from serving as Chancellor and provisions for holding new elections in the event of a deadlocked parliament; all were passed comfortably. Suarez and Carpenter then agreed to call a new election.
While people had their issues with Suarez, most of the public ire fell upon President Carpenter, who was seen as most responsible for the questionable arrangement. By the time her term expired in 2008, though, she had successfully led the country through another period of difficult minority government, this time under Alexander Blackwell in 2007. This earned her enough support to successfully win re-election in 2008, serving uneventfully until the end of her tenure in 2013. Nonetheless, her actions are still contentious and her legacy is mixed.
The USA (or rather the Federal Republic of America) is significantly smaller than OTL USA since the Louisiana Purchase was never made. Here's a map.
