To my surprise his super old vote isn't very strong in the latest poll
Ford: total 27%, (18-34) 33%, (35-44) 23%, (45-54) 28%, (55-64) 25%, (65+) 22%
Tory: total 28%, (18-34) 12%, (35-44) 36%, (45-54) 27%, (55-64) 35%, (65+) 41%
Chow:total 29%, (18-34) 32%, (35-44) 27%, (45-54) 29%, (55-64) 28%, (65+) 29%
Ford rates below Tory and Chow from anyone above 55 and a lot by those over 65. So thumbs up to the gray hairs.
I think they do ask different people, but numbers do flux a bit, that's normal. Going up or down by 2 or 3 is expected. Average and trend is much more important. For the longest time Ford approval was in the mid 40s (45ish) and it stayed there for a long time. It might go up by 3 to 48% which brings the predictable headline "Ford approval spike" but almost like clockwork the next poll will show Ford back to the mid 40s. It's just regular fluctuation of a number. In early May that changed (second crack tap/rehab) when it dropped to low 30's (the new normal) that could be claimed as a drastic change. Since then low 30s is his common number (28-33)
