If your country was the 51st state?

[Wake Me Up When The Hard Border Ends]

Australia, assuming the parties stayed as they are, would likely be solid D, Queensland and Western Australia would be the best Republican states.

If the party platforms were re-aligned to the Australian political spectrum, here's how Australian states and territories would vote:

New South Wales  (13 EV) - Swing state, would have 1 D and 1 R Senator, and gone for Bush in 2000 and 2004, and Obama in 2008 and 2012. Narrowly goes for Clinton in 2016 despite Trump doing well outside Greater Sydney.

Victoria (11 EV) - Historically a Republican stronghold, Victoria would be a bit like New England, having heavily trended Democratic since the Clinton era. Bush would have come close in 2004, especially in rural areas in the east and west, plus the eastern suburbs in Melbourne, but Clinton would have won here comfortably in 2016. Probably elects 2 D Senators.

Queensland (9 EV) - Republican stronghold, would have last voted Democratic in 1964 or 1976. Republicans would hold both Senate seats here now, especially after improving in the rural north of the state. Democrats do well in suburban Brisbane, but not much else.

Western Australia (6 EV) - Another Republican stronghold, Democrats do well in a fair chunk of Perth, and in the Kimberley in the state's north, but Democrats would have struggled here at the Presidential level since the 1980s. Probably 2 R Senators here too, although the Democrats could win one in a good year for them here.

South Australia (5 EV) - Another swing state, more Democrat leaning, and went for Clinton in 2016, probably goes for Gore in 2000 too. Adelaide has generally been more of a Labor city than Perth. Most likely 1 D and 1 R Senator.

Tasmania (3 EV) - In Australian politics, Tasmania tends to beat to its own drum, having been solidly Liberal in the 1980s when Labor held office federally, and vice versa when John Howard was PM. An American Tasmania would have been the best state for Nader in 2000, throwing it to Bush, and while Kerry narrowly wins here in 2004, Trump does so too in 2016. Most likely 1 D and 1 R in the Senate.

Australian Capital Territory (3 EV) - Mega-solid Democratic, they'd hold both Senate seats, but the Republicans still do better than in DC.

Northern Territory (3 EV) - Quite split actually, the NT as it's often abbreviated to has a large Aboriginal population, but as recent territorial elections show, they're not necessarily a solid-D voting bloc. Would probably vote with the winner in most elections (and would have been the site of a recount in 2016). 1 D and 1 R Senator.

At the state/territory level, the parties would be a lot more competitive (WA and QLD, the latter in particular have a recent tradition of electing the opposite party to who's in federally)
