If Hillary, or another potential candidate with money and organization behind him/her, is pushed now, so that there is a constant bombardment of that person's name, identified as a contender, when the primaries actually get here, they'll have more name recognition, and be more likely to poll well, over any other possibilities.

It's a marketing strategy, just like all those commercials on tv.

Those fresh names and faces probably aren't as well organized and funded, and haven't decided to toss their hat into the ring at this point.

They probably aren't included in any polls at this point, either. And, when the primaries finally do roll around, they may have trouble getting any serious consideration from the media and/or pollsters, for these very reasons.
