Yes if he ran as a populist he would totally be president now.
No worries about things he said like...
"Corporations are people"
"I like being able to fire people"
"I'm not concerned about the very poor"
"there are 47 percent who....are dependent upon government, who believe that they are victims...so my job is not to worry about those people—I'll never convince them that they should take personal responsibility and care for their lives"
Those certainly would not have suddenly become even more hypocritical and make his populist campaign completely ludicrous
If Romney had been running a populist campaign he would not have made the above statements.
