If Romney can win the Badger State [Wisconsin] after losing Ohio, he would still need to win Colorado and either Iowa or Nevada to win the election.
He's leaving out New Hampshire as a way for Romney to win. Romney can win Wisconsin, Colorado and New Hampshire to get to 271. Iowa or Nevada can be substituted for New Hampshire. That also seems to me to be Romney's easiest path to victory. That would mean winning 5 of the 8 remaining swing states on Scott's list (CO, WI, NH, VA and FL) and losing OH, IA and NV.
