Bahrain has many historical  and cultural links to Iran. A number of Bahrainis (both Shi'a  and Sunnis ) have Persian roots and speak Persian, and many of Bahrain's Shi'a community regularly travel to religious sites  in Iran. On Bahraini blogs and forums there has been a lot of support expressed for Mahmoud Ahmadinejad , thanks in particular to his reputation as a clean politician and modest person, but he is not popular with everyone.
Rayyash  wanted Ahmadinejad to win:
وعودا الى نجاد المتواضع والنزيه والذي كشف عن ميزة جديدة وهي الشرس !! حيث كشر عن أنيابه في المناظرة التلفزيونية مع خصومة ولكنه لم ينجح لأنه ناقش في الخصوصيات والامور التي لاتمت للسياسة بصلة وهي ضربات تحت الحزام ما كان يتوقعها منافسوه!! ولعلها كشفت بكل جلاء أن في السياسية ترفع جميع الخطط الحمراء والشرعية !!!
Returning to the modest and honest Ahmadinejad, we see that he has revealed a new quality, and that is his ferocity! He bared his fangs in the televised debates with his opponents, but he did not succeed as he discussed private matters and issues which had nothing to do with politics, and which were hits below the belt – that his opponents did not expect! This clearly shows that politics removes all boundaries and propriety!
On Bahrain Online, the most popular forum in Bahrain, Tammuz commented before the election results were announced :
On the same thread, Al Shafaq says :
كم احب هذا الرجل المتواضع
اتمنى ان يعرف الإيرانيين قدر هذا الرجل
On another thread, Athbat Al Oyoun says :
Ali Abdulemam is no fan of Ahmadinejad :
I used to call Ahmedi Najad the crazy, even when i was in Iran talking with my cousins while we are talking about his politic, i used to call him crazy so i mean no harm to all of you.
honestly i was supporting mir hussain mosavi because i feel Iran will need a presedent like Khatami , more freedom, more respect, freedom of choices to be made…this is what i believe not in iran only but in every where in the world, but at the end, we are not iranian, we have to respect this crazy [man] when he come to the power and we have to deal with him for the next four years
I was following the election by persian blogs, thanks god i know persian so it was easy for me , the strange things i discovered is, Najad failed in economic area, and its reflecting the poor people which is the majority in Iran, but the poor majority didn't talk about economy as its one of their criterias , these were talking that Najad is clean, we need to vote for clean people
