The Voter Contact Program

While other candidates are making bids from the heart, Mitt Romney's political strategies are purely cerebral. His funds go into research at a far larger margin than any other candidate's can. His researches study voting patterns, demographic shifts and voter compatibility (to what speech Romney would be making that week.) He pays particularly close attention to financial trends and records, since most of his campaign is based on his business experience, and not on social values. All this effort is worth the cost, since it definitely gets results. Romney has found a way to target specific groups for support months before a primary begins, and they don't disappoint him on voting day.
He targets older and higher income families with a strong interest in children and extra-curricular activities. The type of people that might be the head of their PTA, or a regular at the country club golf course. They are usually staunch Republicans, but not necessarily die hard church goers. Being a Mormon is still a huge drawback for Romney in states as conservative as South Carolina, so his volunteers don't waster their time focusing on Evangelical voters, even when they make up about 60% of the state (as they do in SC.) They know that they other candidates can split that vote, leaving a whole 40% left for Romney.
When making calls or going door to door, volunteers are trained to listen for interest from voters in economic issues, but also border control and welfare programs. Romney takes a pretty popular views on these issues, ones that are shared by his fellow candidates. The idea is that if a voter is still undecided, they can make Romney seem just like his fellow candidate but only an improved version. So, if they are considering someone else they might think 'I agree with this, but Romney has the same view PLUS the economic experience. I will choose Romney.' The concept is so simple, I'm amazed it's news.
And that is what Romney needs, simple support. The nomination is his if he just gets people to the polls.
