The large room is packed with people of all ages. Beside me is an undecided voter who is very concerned about healthcare and Iraq. She just attended the funeral of a friend, a 22 year-old Marine who died in Iraq. She says there's no good answer for Iraq, but that we should respect our soldiers and their sacrifice. She's heard Obama before, and is now looking forward to hearing from the others. Like many in Iowa, she is "shopping" for the right candidate. Her number 1 criteria? Electability.
