Ashtar, beautifying a city and maintaining it, building parks, paving streets, new autobans, are all the legacy of Karbaschi's modern, efficient, and caring management style. Neither I nor anyone else who has lived in Isfahan or Tehran has anyhting to say but praise for Karbaschi and his team of managers for what they accomplish in two large cities of Iran.
AhmadiNejad, had even larger budget than his predecessors not only due to better tax collection (thanks to state), state financial help to capital Tehran, but selling lands as well, but irrespective he miserably failed in flood and snow control, traffic management, and to some degree even garbage collection.
No it is not the mayor's job to act as a wellfare department, his job and what he is hired for is to to run the city and leave the wellfare to social workers. But again, pretencious behaviour is a trademark of 'Hojattieh and associates.
We all know how he got his presidential votes, it was vote rigging organized by IRGC and Basij illegal acts (admitted by Khatami, Rafsanjani, Karubi, Moin,..) and as AhmadiNejad mentor, MesbahYazdi put it "hands of Imam Zaman."
So, if the IRI officials after the facts, decided to ignore the wide spread vote rigging and cheating for sake of regim survival, people don't have to forget their initial comments.
Anyway, one need to wait a few more years before judging AhmadiNejad and his 3% voted city council conducts eventhough they benefited greatly from initial works and foundations Karbaschi laid in both cities, but it takes just a short longer to see if they could add positively anything to his legacy or reversed his initial improvements.
Of course, AhmadiNejad himself will be under bigger magnifier as president. By the way, the rumor (probably even very true for populist agenda) of $5 billion imports is from 'BaztAb' close to IRGC and religious right.
