You may be right that Romney and Paul may grab all the delegates there. Hopefully the media won’t give the caucuses prominence even if they do run the occasional story such as this one.
The news starved media definitely will report it. But even if Maine were to be largely ignored:
The regional media (Boston Globe, etc.) will report heavily on it, so Romney gets a boost in MA VT RI CT NY. That is a minimum.
If a caucus is held in the forest and nobody hears it, did it really happen?
It is delusional thinking that this early in the race nobody will notice that Newt and Santorum combine for 4% over the first 7 days.
