Whoever wrote that is functionally illiterate.
The chart itself is labelled:
"Numbers of countries with majorities or pluralities saying:
A lot/some confidence (vs) No/Not too much confidence".
The source for the chart is at:
http://www.worldpublicopinion.org/pipa/articles/home_page/488.php?nid=&id=&pnt=488&lb= It's a country-by-country survey of something like 20 countries. Of the twenty surveyed, some give more credence to Neejad than Bush. Most don't. But in few do more than 50% or a plurality of the respondents place "some/a lot of" confidence in Neejad or Bush. Few "world leaders" get more than 50% at all.
To be precise, Bush "wins" in two countries, one because he got over 50% (I don't think he was top scorer, though), and the other through a plurality, i.e., he got the highest percentage of all "contestants": Nigeria (> 50%) and India (45%).
Neejad wins 3: Indonesia (40%), Palestinians (37%), Jordan (24%).
Note that while Iran rooted riotously for Neejad, he was "local" to them and therefore didn't qualify. Oddly, Bush was listed as "world leader" for the American survey, but Brown won that (59% to 42%), so that quirk didn't skew the results.
It's not a good result, but let's at least not display our functional illiteracy for everybody to see, ok?
