That's not correct. The Iraqis voted for lists with delegates for Parliament. It was for months unclear who will be designated Prime Minister by the winning parties. Jafaari and Abdul-Mahdi were for a long time the most likely candidates. But your point is valid nontheless. It is up to the Iraqi parliament and the parties to change or maintain the government, not Dem senators.
Thanks for correcting me, wouldn’t want to state misinformation. And thanks for recognizing the underlying point I was making, even though premised on a misunderstanding of their election process.
