Looking at where I live, Tandridge (which is effectively the East Surrey parliamentary constituency), I think the Indies are mostly NIMBY 'Tories'. When it comes to Westminster elections the Tory gets around 60% of the vote. Sadly, I don't see that changing too much. The only parliamentary party other than the Tories with any strong support is the LibDems and they are way behind.
Perhaps, in other areas in the South East where there's a stronger presence of Labour or the Greens as well as the LibDems things might be a little different.
In West Sussex I am sure the Tories will hold 6 out of the 8 seats, where they have majorities of around 15-22,000. But, it's possible Labour could take Crawley (maj 8,360), they held it from 1997 to 2010, and perhaps East Worthing and Shoreham (maj. 7,441) - Labour was second in 2015 with about 10,000 votes, but in 2017 & 2019 they got around 20,000 votes, and they are working very hard in that area.
East Sussex the ones at risk are - Lewes (maj 2,457) will probably go to the LDs who held it 1997-2110, Hastings and Rye (maj 4,043) to Labour who held it 1997-2110,
Eastbourne (maj 4,331) to the LDs they took it in 2010, lost it in 2015, took it back in 2017, lost it again in 2019, so I guess it's their turn again.
Brighton & Hove's 3 seats are safe for Labour & the Greens, leaving the Tories possibly only with Bexhill and Battle + Wealden where they have majorities of over 25,000, i.e. just 2 out of 8 seats.
In Kent I suspect Labour will keep Canterbury, where they overturned the Tory majority of around 10,000 in 2017. I suspect the only other at risk is South Thanet also with a Tory majority of around 10,000, Labour is in second place and held it 1997-2110. Maybe Dover 12,000 majority, but again Labour held it 1997-2110. The rest seem safe as houses.
If around 10,000 majorities are at risk, in Surrey that's -
Esher and Walton - 2,743 - LDs in a strong second place, and people may want to give Dominic Raab a good kicking.
Guildford - 3,337 - LDs in a strong second place, and held it 2001-2005.
South West Surrey - 8,817 - LDs in second place, and people may want to give Jeremy Hunt a good kicking too.
Woking - 9,767 - LDs in second place.
So, a fair few at risk across the four counties, it's certainly going to be an interesting.
I can't believe how much time I wasted on checking all those out, but it's pissing down, and I am avoiding some bloody unmentionable event that's happening in that there Londinium.
