According to The Australian newspaper -

Scott Morrison faces losing his parliamentary majority
unless the Liberals choose a female candidate for the
Wentworth by-election according to private polling -
showing the government's primary vote has crashed to 39%
in the blue-ribbon seat vacated by Malcolm Turnbull.

The polling taken at the week-end and paid for by early
Liberal front-runner Andrew Bragg (who's since withdrawn)
showed that a female candidate would boost the Liberal vote
in the seat by 4%.

Malcolm Turnbull polled 62% in Wentworth at the 2016 election
but the Liberals now face a back lash over his dumping as
Prime Minister putting the Coalition's one seat majority in
jeopardy.

Dr Kerryn Phelps , an Independent, is another candidate who
may consider running for the seat in Wentworth. She would
be a formidable candidate as she's well known and very
popular in the area.

Interesting times ahead.

Call me a bigot, sexist or a chauvinist, but I for one, would not like to have a raving lesbian feminist , to represent any one of those in my constituency. Imagine, you'd have all the left leaning labour policies implemented. Anyway I think we can all rest fairly easily, given it's a pretty conservative electorate.

The electorate of Wentworth had the 4th highest YES
vote (80%) for same-sex marriage. The electorate's
huge vote for same sex marriage shows that a conservative
Liberal candidate might not be certain to bin a bye-election.

Ton Abbott's gay sister was going to run as an Independent,
then changed her mind.

Samantha Maiden on Twitter has stated that "Kerryn Phelps
will run in Wentworth and many senior Liberals believe she
will win. So there will be a female member for Wentworth
but not necessarily the one Andrew Bragg is standing aside
for on the promise of entering the Senate in a winnable
spot."

Dr Phelps is well-known and is a very credible Independent
candidate. She's also very popular in the electorate.
She's in with a good chance as there could be a backlash
against the Liberal Party's candidate due to the
dumping of Malcolm Turnbull as PM.

Putting up a female candidate just because she is a female would be the height of stupidity; nonsense best left to the Labor party. No self-respecting, proud woman would allow herself to be used that way, so any woman fronting up would be a dud. Because of the rubbish about quotas, ALL women in politics will always suspected of being second rate; and any woman who goes into politics knowing that WILL be second rate.

When Margaret Thatcher was asked what it was like being the first female prime minister, she said that she didn't know, because she had never been a make prime minister. There have been capable women in politics, and there have been pumpkins, e.g. Gillard here and May in the UK. The idiots who have made a huge thing out of female quotas have done nothing for women - in fact they have made female politicians suspect for all time.

At the present time, woman wannabes of inferior of average ability know they cannot compete with men, and that they need to have the field cleared of men to be elected.

Here's a remark from someone on twitter that's
appropriate:

"Mr Bragg's claim he selflessly stood aside for a
woman at Wentworth...

He gets a safe Senate spot and a woman gets to fight
for the government's life in a marginal seat!?

Interesting.

Hard one this, the Wentworth by-election. If I was having a vote on Thursday for the Liberal candidate, and I don't think they let Greens vote, I'd plug for Michael Feneley, who is well known to me. Michael's gone round more times in elections than the spin dryer in a washing machine.

Make it clear, Labor can't win Wentworth, Belly might not agree, but that's the reality. Turnbull was popular in the area, his personal vote was based on being PM and an economic conservative with good business connections, which endeared him to the old money around Vaucluse, where the Libs pull 80%-90% of the vote. Turnbull was seen as a enough of a social progressive with an economic conservative slant to satisfy the well heeled kids from up Paddington way, where the Libs are good for 70% of the vote.

Who can win? The Liberals, obviously have the best chance, but a high profile Independent woman, like former AMA President Dr Kerryn Phelps with a low Liberal primary vote, she would require a strong preference flow from Labor/Greens to win. Could happen.
