Julia Gillard has annouced the Australian election for 14th September 2013, which is Yom Kippur
Personally, I don't have an issue with it. The election always falls on a Saturday, which observant Jews will not vote on anyway.
The fact is that most Jews will observe Yom Kippur, but not every Shabbat. Michael Danby was not happy, and stated he would not campaign. Mark Dreyfuss announced a similar message also. Some Jewish people that would usually campaign on election day were disappointed. Kelly O'Dwyer wrote a long letter to the Jewish News to campaign.
As mentioned, I have no issue with it. I think that anyone who can't vote should register for a Postal vote now, and why not register for every year while you are at it. The link to register for a postal vote is here.
