Yes Obama leads Romney in popularity 50%:9%
This is from a poll conducted by Globescan/PIPA for the BBC World Service in 21 countries between July 3 and September 3, with an average of just over 1000 respondents per country (total 21,797)
The only country where the people would prefer to see Romney as President is Pakistan, most likely as a result of the highly unpopular drone attacks. Obama has second least popularity in China, surely indicative of the strong stance he is taking on trade issues.
The only country where Romney has any real "foreign policy" experience, France, is the country where Obama is most popular with 72%. That though is not Romneys lowest popularity score, than honor goes to Spain.
Surprisingly the country where Romney has his greatest popularity is ........Kenya! Although even there he gets under 20% rooting for him.
