Which numerical rating scales have pro pollsters used to rate politicians?

[Warren D Smith]

Searching a large international poll database by the ORS
for range-style polls using various numerical scales for
people providing overall-ratings for politicians [as opposed to other
topics such as about "named politicians just on abortion" or "blacks"
or "terrorism"]
I found these score-ranges were used:
1-4
1-7
0-100
1-5
1-100
1-100
1-10
0-10
but no others.

No polls were found using negative numbers. Have not investigated
(<=3)-level scales, but
tried every reasonable possibility 0-to-X and 1-to-X with 4 or more
levels, also tried "negative X to Y" and "minus X to Y". There were
many nonnumerical verbal scales like "negative view, neutral, positive
view" and "favorable, unfavorable" which were both-signed, so in
that sense negative numbers happened.
