1. Hartlepool was behind the curve in #GE2019 & the by-election represents catch up. 2. #Brexit realignment of British politics is still continuing.
Let's look at them... /1
The 1st can be confirmed just by looking at CON vote share changes between 2010 & 2019 in Hartlepool's 4 neighbours.
Easington > from 14% to 26%
Sedgefield > from 23% to 47%
Stockton N > from 26% to 41%
Redcar > from 14% to 46%
Hartlepool > from 28% to 29%
So the jump ...
/2
... to 52% in this by-election can be put down to #Hartlepool copying its neighbours 2 years late.
But could this indicate the Brexit realignment of 2019 was incomplete & there could be more Hartlepool's?
The answer is yes. Note how nearly all BXP voters went to CON ...
/3
... in Hartlepool.
How many more LAB seats could CON win if all BXP+UKIP voters switched to CON?
Answer is 35 where CON is already in 2nd place to LAB.
The list is shown below with seats ordered by the combined BXP+UKIP 2019 vote.
I've not included the 2 Barnsley seats...
/4
... & Blaenau Gwent where BXP is 2nd to LAB.
To see if it's feasible for all BXP+UKIP voters to switch to CON, my table above has a LV DIFF column.
This is the difference between a Possible CON19 share & actual CON19 share.
Possible CON19 = 0.7 * %LV16 + 0.2 * %RM16
I ...
/5
... used this Possible CON19 as 1 of 7 models I used in my #GE2019 forecast where I was the most accurate forecaster (see bit.ly/2Q2qepM).
The 70% & 20% came from what the final polls said (bit.ly/3b9KbCu) and latest polls confirm this is still the case...
/6
So Hartlepool, since it voted 70% leave, 0.7*0.7 + 0.2*0.3 = 55% is the Possible CON19 share.
Since they got 29% in 2019, the LV DIFF is 55-29% = +26% as shown.
They actually got 52% in the byelection which means there was 3% spare.
As my table shows, 8 of the other 35 ...
/7
... have spare votes less than or equal to Hartlepool & are probably not at immediate risk.
The other 27 though must be regarded at risk for LAB if polls remain where they are today.
Top of list after Hartlepool is Ed Milliband in Doncaster.
Next is Hartlepool's neighbour.
/8
... Easington, 1 of 7 more NE seats that are vulnerable.
As bad as it is for LAB in NE, it's even worse in Yorkshire where 11 seats will be firmly in CON's cross-hairs.
So to repeat, #HartlepoolByElection was definitely a case of the seat catching up with the red wall...
/9
... collapse of #GE2019 and keeping up with the Joneses.
But before we get onto the question if the Brexit realignment is still continuing today, Labour has to shore up its defences in at least 27 seats that will share Hartlepool's fate unless action is taken.

Parliament votes tomorrow to confirm that England will go into its 2nd #COVID19 lockdown from Thursday. Does the data show that it's necessary?
We know that deaths are rising and at present are on trend to overtake the April peak around the 3rd/4th week of November.
But ...1/n
... if cases are already in decline by now, then what will a 2nd lockdown do to help reduce deaths?
At best all it can do is accelerate an existing decline or at worse prevent cases from increasing again.
So are cases about to turn? Nationally, the picture is poised. /2
The 7 day centred moving average has turned but potential revisions to the last 7 days could reverse this (red triangles are a short CMA projection based on previous restatements).
The thing to note though is that the latest 7 day CMA is as of 26th October, 1 week ago.
This the 59th presidential election in USA and the 56th competitive one.
3 elections saw a candidate elected unopposed 1789, 1792, 1820.
1/n
Of the 55 competitive elections, 36 saw the winner win a majority of both the electoral college (EC) & popular vote (PV).
One, 1800, needed a contingent election in the House of Representatives as well, an oddity that led to the 12th Amendment that could play a part in 2020.
/2
14 of 55 competitive elections saw the winner take the majority of the electoral college with a plurality of the popular vote.
Lowest PV share to win an EC majority was 39.8% by Lincoln in 1860 (his name was not on the ballot in the South) followed by Nixon 68 & Clinton 92.

They were preceded by decades of debate on the use & misuse of P-values & the UK's relationship with the EU.

In September 2016, I attended the @RoyalStatSoc conference in Manchester. #Pexit was a keynote session where @AmstatNews gave its reasons for its statement.
Are we going to see a repeat of #GE2017 ? In my Friday post marriott-stats.com/nigels-blog/uk… summarising latest poll trends, I said Labour need to focus on C2DE, Leavers & Lib Dems.
With the polls we've had over the weekend, this thread summarises what I am seeing. /1
CON-LAB lead is unchanged from the start of the election since both LAB & CON are up 7 pts. If this remains the case, it will be a Conservative majority.
Note figures for the latest week includes some from end of last week. My week is defined to be Thurs-Weds. /2
LIB DEMS 1 - Labour needs to first recover its #GE2017 voters lost to the Lib Dems. Having lost 40% of LAB17 voters by the time Theresa May stood down, they've recovered a third. Of the remaining 2/3, half are still with LD&GRN and half with CON&BRX. /3
