The NHS has gotten worse over time, under the fag end of the last Labour government, under the coalition government, and under the Tory governments since 2015.
Unmanaged immigration - legal and illegal - puts pressure on public services, including the NHS. That is just a fact that cannot be swept under the carpet.
A good proportion of those who will depend on the NHS in coming years will figure this out and vote accordingly.
And please withdraw your accusation of me blaming immigrants - I did no such thing.
I actually blamed the UK's high population density plus the immigration policies of successive UK governments, not the immigrants themselves.
