Poll in two languages
I've solved my problem as follows:


Download the i18n patch from here
Apply the patch using any preferred technique, you can refer to Drupal
Applying should be on a test drupal installation in order to avoid any problems
After that go to modules page and enable the Poll Aggregate module under i18n, this will synch the voting results for all installed languages
After testing the patched module and getting happy result, install the module on your live site.


I have test this solution and it is OK with some small problems that I am trying to solve, and I will share the new things.
