On the second floor of a Sydney pub, the mood shifts from nervous, browser-refreshing anxiety to champagne-popping within a matter of hours.More than 100 US expats and election enthusiasts pack into the function space at the Keg and Brew in the inner-east suburb of Surry Hills to watch the midterm results roll in.They’ve followed a sign reading ā€œDemocrats Abroadā€ guiding them upstairs on Wednesday lunch time when live reports began broadcasting on the pub television screens.Early on, American voters, their Australian partners and British spectators said they were ā€œcautiously optimisticā€.Within a couple of hours in, news of the Democrats’ historic win dramatically shifts the mood.Katrena Henderson, from North Carolina, says she has ā€œnot been this excited about an election in a long timeā€.Sitting with her Australian husband and adult son, the trio chronically refresh their phones for results and celebrate when her Senate seat flips to the Democrats.Katrena Henderson, a North Carolina voter, says the significance of this election has prompted her to make a political donation for the first time.

And they won decisively,ā€ she says. ā€œIt just really points to the fact that Americans want something very different, because this administration is not working for us.ā€œI think what we didn’t have before today was a lot of hope … and at least now there is some hope.ā€Associate Professor David Smith at the University of Sydney’s United States Studies Centre, says the midterms are a ā€œreferendum on Trumpā€. He says the writing was on the wall as voters went to the polls with the president’s approval ratings at a ā€œhistorically lowā€ level.ā€œAll year, I think Americans have been frustrated by Trump’s lack of focus on things that matter to most Americans,ā€ he says.ā€œWhether that’s the war in Iran, which most Americans didn’t want and which have sent prices up in a pretty direct way, or whether it’s Trump’s constant beautification projects in Washington, D.C. … All of this is just evidence to a lot of Americans that he is focused on the wrong things and he’s focused on his own self-aggrandisement rather than the country.ā€Cindy Herman-Jones moved to Australia from Texas almost 15 years ago and has never cast a vote while living abroad.

She says she was compelled to mail in a ballot because of ā€œthe stakes of this electionā€ were too high.ā€œDemocracy itself is being attacked by the Trump regime,,ā€ she says. ā€œI just feel like they’ve done so many terrible things, and if he’s in power for another two years with no check on that, then it’s just going to continue to get worse and worse.ā€In a list of the ā€œmany terrible thingsā€ Trump has done, Herman-Jones points to the increased ā€œbrutalityā€ of ICE immigration enforcement and the US war in Iran – which she calls ā€œthe worst thingā€ he’s done.Her vote towards Senator James Talarico saw him flip the Upper house seat, and ā€œamazedā€ to see him win because ā€œit’s such a hard job for a Democrat to win in Texasā€.Aliana Hensel is another first-time voter. The 18-year-old Californian has lived in Australia for about eight years with her American parents.She says that while her parents ā€œdon’t generally voteā€ and have not voted while abroad, it was something she wanted to do because ā€œsomething really, really needs to be doneā€ about US leadership.Aliana Hensel, 18, voted for the first time in the US midterms.

I wasn’t old enough to vote in the presidential election, but I watched that, and it was quite the disappointment,ā€ she says. ā€œSo I’ve been very focused on knowing that I can vote this time and wanting to make a bit of an impact.ā€Just a couple of kilometres to the north of the Keg and Brew, a small group of election watchers gathered at the Cheers pub off Sydney’s George Street in the CBD over schnitzels and pints of Guinness.The event was posted as a meetup for some Republican expat groups, but attracted more of a mixed bag of libertarians and independents interested in the drama of an American election.ā€œIt’s interesting to me to see how the populations in America are responding to their situation,ā€ Rahn Wood, 60, an Australian who splits his time between Sydney and Vietnam, said. When asked if he thought Australia and other nations looked towards America when it came to political decisions, Wood said Trump’s influence had a long reach.Australian Rahn Wood, 60, at a US midterms election watch event at the Cheers pub in Sydney CBD.

Many had wandered off after lunch.Professor Smith says while the election ā€œcould have significant ramifications as far as things like the Iran war goā€, he doubts it will directly influence Australia or Albanese’s relationship to the US because ā€œcongress, at the moment, doesn’t have a very big role in foreign policyā€.Smith believes the most interesting is what happens to ā€œTrumpismā€.ā€œThere are lots of politicians around the world who take their cues from Trump, including in Australia … If this is an election that really shows the limits of Trumpism in the United States, that could potentially make a few rightwing politicians worldwide rethink how much they want to be tied to Trump,ā€ he says.
