Poll Roundup: Ghosts of 1996 and 2007 Edition

2PP Aggregate: 54.1 to Labor (+0.9 since last week)
(Weighted for time only, no house effects or quality weightings)
If the normal range of polling to result relationships applies, Labor is very likely to win

I've been very time-challenged this election (expending much of last night refuting an American know-all and sundry reply-guys about our preferencing system on Twitter probably didn't help) but finally, maybe, I can get something out in time for an article about the state of national polling. 

As an overall summary, Labor suffered alarmingly rapid losses in support during the first week and a half of the campaign as documented in the previous edition, but the Coalition's position did not improve over the next two weeks, and now in the latest round of polling there has been a bit of a blowout.  Labor's lead is so large now that the Coalition is extremely unlikely to win by normal means.  What hope remains for the current government is that the polls are even more wrong than last time (despite everything some of them have done to repair it) or that they are about or nearly as wrong as last time and the government makes some improvements over the final week and a half then gets lucky with the seat distribution and scrambles back, perhaps with a sub-50 2PP.  It's not all over yet, but on the other hand the prospect of a decisive Labor win is much stronger now than it looked even three weeks ago.

Poll Roundup: Lukewarm Budget Reception As Coalition Remains Way Behind

FIVE POLL AVERAGE 54.6 TO LABOR
Little evidence of "budget bounce"
Labor would comfortably win election "held now" 

Leads in polling at this stage tend to contract

Herewith a roundup of polling following the Budget.  It's been a long time since I had time for the last federal polling roundup here, so I just want to set the polling scene before moving on, time (what is that?) permitting, to Tasmanian House of Reps seat guides, a Tasmanian Senate guide [EDIT: that will come after nominations are released] and hopefully a general assessment of the prospects for the Senate.  In short, the government's current polling is rather bad, but it is not all over yet.  To take things pollster by pollster, with the three who are Australian Polling Council members at the top and the laggards and backsliders at the bottom:

2019 House of Reps Postcount

Coalition has won the election, almost certainly with a small majority

Apparently won Coalition 77 Labor 68 Green 1 CA 1 KAP 1 IND 3. 

Seats Assumed Won By Coalition From Labor: Longman, Herbert, Bass, Braddon, Lindsay
Seats Assumed Won By Labor From Coalition: Gilmore, Corangamite, Dunkley
Seat Assumed Won By IND From Coalition: Warringah
Seat Assumed Won By Coalition From IND: Wentworth 

Seats that were being covered but now assumed won: Boothby and Chisholm (Coalition retains), Lilley, Cowan  (Labor retains), Bass (Liberal gain), Macquarie (ALP retain)

This is the main thread for the 2019 House of Reps postcount.  A few days ago I expected I would be unrolling separate threads to unravel three-cornered contests in Melbourne, a complete mess in Mallee and so on, but at this stage none of that has happened.  I have done a quick thread for Mallee though as there's some interest in it.  There is a weird situation in Hunter, where One Nation are currently two points short of beating the Nationals into second, but I don't see any reason to think they can get into second, let alone win if they do.  Indeed the Nationals' margin in second should increase.

Poll Roundup: 2018 Year In Review

2PP Aggregate: 54.2 to Labor (last election preferences) (+0.2 since two weeks ago)
With One Nation adjustment: 53.6 to Labor
Labor would easily win election "held now"
Labor won all 66 public and three commissioned national polls released this year

With the release of this week's Ipsos and Essential polls, the polling year has probably come to an end.  If there are any late polls I will edit this piece and update it accordingly.

For a government that currently looks as stuffed as a Christmas turkey, the end of the year cannot come soon enough.  As the final poll of the year, Essential offered some respite having the government only six points behind (47-53) but this should be treated with some caution as there is an ongoing difference of opinion between Newspoll and Essential as to just how bad the Morrison government's situation is.  Since Scott Morrison became Prime Minister, Newspoll has had the Coalition primary on an average of just 35% and the Labor primary on 40%.  Essential, however, has had the Coalition primary only narrowly behind (on average 36.9-37.2).  On a 2PP basis Newspoll has had an average reading of just 45.25% for the Government, while Essential has had 46.6% - and this is even though Newspoll's preferencing method is more favourable to the Coalition's than Essential's.  Currently, with Newspoll and Essential coming out in different fortnights, my aggregate bobs around a bit depending on which one is out, rather than based on the Coalition making substantial gains or losses.  If this continues into the New Year I may apply corrections to both.

How Many Lower House Seats Can The Xenophon Team Win?

Note: For links to updated analysis re NXT written since this article, scroll to the bottom.

I have had a fair few questions about the Nick Xenophon Team (NXT) and their seat prospects for the Lower House in South Australia, because my seat projection nationwide still shows only four seats for Others.  This rather dry and mathsy piece (about Wonk Factor 3/5) explains my initial attempts to model what sort of vote NXT needs in South Australia, all else being equal, to win one or more of the 11 Lower House seats in the state.  These are very broad-brush attempts that don't take account of candidate factors, because until there is specific seat-polling we don't know anything objectively about how well (or badly) specific NXT candidates are going to campaign or be regarded.  Comments based on detailed local knowledge are welcome.

In summary, I estimate that NXT probably need a statewide vote in the very high teens to win seats.  Once they get well over 20 they start to win multiple seats, and something in the mid-20s could result in spectacular seat gains that would make a national hung parliament quite likely.  However there's no reason yet to believe those higher votes will actually happen, based on what little current public polling of the NXT vote exists.
