“Iowa is a must-win. Its hard to see how Romney can get a majority in the Electoral College without Iowa.”
He could do it, IF he had Ohio. With Ohio, Romney would not need either Iowa or Colorado.
However, without Ohio, Iowa -and- Colorado become VERY important, as they will provide the electoral votes Romney needs to get over the top. (This assumes Romney also gets New Hampshire, which seems to be leaning in his favor).
Ohio still remains “the key”. If Romney wins it before midnight, the election will be his.
Based on the RCP map, Romney can lose Ohio, Penn., Wisconsin and Michigan and still win the election if he gets Colorado, Nevada, Iowa and New Hampshire. He only needs to win ONE of those 4 if he gets Ohio or Penn. though. Something tells me he should bombard Iowa and New Hampshire, and use the Mormon leverage in Colorado and Nevada, rather than pin his hopes on Ohio. The industrial states seem to be giving Romney a harder time.
