Didn't hear about the poll, Gonzo, but assuming it was Scottish candidates only, wouldn't surprise me. You could mark almost certainly all Green and SNP candidates down as anti Trident, probably a majority of Lib Dems, possibly 50/50 on Labour, and then nearly all the Tories and UKIP for it.
Some Tories might have been against it, notes Michael Portillo is now anti renewal. The one Labour MP, Ian Murray, would have been against it, though as noted elsewhere he may now vote for it as being Shadow Sec of State he is bound by collective responsibility
