24% of 18-34 and 34-55 support the truckers and what they are doing

27%/26% support them but not the way they are doing it

49%/50% think they are completely wrong and need to be stopped regardless

There's no real difference between young and middle age, although over 55s skew significantly to "stop them". Not much difference on income, but educational attainment shows significant skew, with university educated far less likely to support the truckers
