More people who are indecisive and insecure, perhaps
I'm not sure how I feel about that but I think that it scares me 😉
There just isn't the Labour culture down here that exists elsewhere. You find little pockets of it in places like Devonport or Exeter but they are reasonably similar to other industrial cities where Labour strongholds have established as a result of strength through unity and trade union influences (particularly in the Plymouth dockyards). Much of the area is still rural and the threat of eviction from landlords that didn't get their way was likely for many people who didn't have the mass support that working people had in the cities. I think that its pretty easy for city based socialists to sneer at the apparent forelock tugging of working rural folk but the truth is that they never been in a position to empower themselves and when they did try, look what happened (Tolpuddle).
The demographic of certain places in the west country has chaged and large conurbations like Torbay are made up of many people who have moved from elsewhere in England and Scotland, however, it still doesn't seem to have made much of a difference politically and in most areas a vote for Labour is as good as a vote for the Tories so most Labour voters here vote Lib Dem which probably adds to the perception of it being a Lib Dem stronghold.
That's my take on it anyhow.
