The relationship between US elections and M.E major events!

Salam, Disclaimer: I'm happy to see Saddam gets his punishment on earth for all what he did towards his people. Now that I got that out of the way, have you ever wondered why major M.E events occur usually on the eve of major U.S elections?! In 2004 Presidential elections, the night before the major elections when the democratic party was gaining on the republican a video tape of Bin Laden comes out of the blue admitting for the first time that Bin Laden is the mastermind behind the September 11th, and with this new fact the American voters were reminded once again of the big bad guy and we all know when in fear vote for Bush. Back to 2007 primary elections, howcome it took the new Iraqi government all this time to hang Saddam?! Why on the week of the elections? is it another boost for the republican party? Don't mind me I'm just thinking loud, maybe it's all just a figment of my imagination. Peace
