Insurgents in Iraq had vowed to disrupt the election, and the attacks appeared timed to frighten voters away from polling sites. If that were the intent, it did not succeed entirely.
Classic false flag. The US and the current puppet regime in Iraq are terrified that they could see a repeat of the Gaza election, in which the Palestinians refused to vote for the "approved" party, so inevitably we get false-flag terror attacks to be blamed on the opposition.
But think about it for a moment. The opposition NEEDS the support of the public. Any group working to change the system needs public support. They are not going to go out and commit acts that alienate the very people whose support they need.
That is why these bombings are all deadly hoaxes intended to demonize the threat to the US puppet regime.
