Why don’t people skip Iowa?

According to Alexander Bolton in The Hill:

Political experts in Iowa say top-tier Republican presidential candidates are facing growing pressure from two social conservatives who may grab one of the “three tickets out of Iowa” because of greater organizational strength.

As a result, candidates such as Sen. John McCain (R-Ariz.), former New York City Mayor Rudy Giuliani (R) and former Sen. Fred Thompson (R-Tenn.) will have to decide whether to invest more time and money in a state they had hoped to survive easily on the way to more favorable contests.

Isn’t the answer to cut bait? There will still be press, if just because Hillary Clinton may well be in a death-match with John Edwards and Barack Obama. But if the Democratic field clarifies and the leading GOPers don’t participate, will anyone care about Iowa?
