Yes this is completely wrong. Every bit of quant and qual shows people are far more worried about small boats than legal migration for work/study.
"On the doorstep people don’t make a distinction between graduate visas & small boats"
This is:
a) objectively wrong (plenty of polling evidence)
b) suggests utter contempt for electorate's thought processes
c) is a dreadful way to make policy
Otherwise fine
