Yes, the thing with polls is they don’t tell you whats happening in individual seats, It’s highly unlikely they would get anywhere near the 13 seats they got in Scotland no matter what the polls say. The triple whammy of Brexit, Johnson and Davidson they will be lucky to get 3.
They will have seats they have taken from the Liberals recently a few Brexit party votes will see them swing back. So 34% doesn’t translate to seats. Its 3% down so if they lose seats to SNP and liberals they would need to be the main beneficiary of lost labour seats. I have no idea how many labour seats Conservatives were in second place and were winnable.
There will be no working majority either way so it will depend on those best placed to make deals and the tories only have the 10 or so DUP seats to count on.
