@CanadianPolling Kind of wrecks the comparison if they include "Cannot say" in 2026.
If you remove "Cannot say" from the data, 2026 looks like:
Strongly oppose: 63%
Somewhat oppose: 10%
Somewhat favour: 12%
Strongly favour: 15%
It puts it more or less in line with the 2003 and 2005 results.
The new table makes use of "scanner data" (I.e. the actual recorded transaction cost/payment) whereas the old dataset made use of posted prices in store.
So,
old prices: what was advertised in store
New prices: what people actually paid at the counter
