Mitt Romney leads the PD Composite by himself for the first time since its inception as Newt Gingrich’s drop in the polls has mirrored Herman Cain and Rick Perry before him. Romney’s long-term national race strategy seems to be working in his favor as he is the only consistent candidate in the top-tier.

The 17.6 point gap between second place Gingrich and the rest of the field is quite significant, with Ron Paul barely making it over his normal 8-10 percent range on the back of his significant Iowa popularity. The rest of the field is below 10 percent and will need miracle finishes in one or more of the early voting states to give their campaigns a jolt of life. Otherwise, we may be well looking at only three horses in this race within a month.
