Iowa has gone for Huckabee, Santorum, and Pat Robertson for gods sake. Pat Robertson??? Really?
No, not really. Iowa went for Bob Dole that year, not Pat Robertson.
Also, Santorum and Romney effectively tied, with each getting 25% of the vote. Santorum did edge out Romney on a recount, barely.
Terribly tragic all this attention is given to Iowa and to their long shot candidates they pick. ...
Get your facts straight. For the last ten cycles, Iowa Republicans picked the eventual GOP nominee six out of ten times (not counting the near-tie with Santorum and Romney). Besides Huckabee and Santorum, the other two times Iowa Republicans missed they instead picked Bob Dole (again), and George H. W. Bush. Those are hardly long-shot candidates.
Not only because they consistently chose the wrong guy, but way too much attention is given to that state for no practical reason.
On the contrary, the very practical reason Iowa and New Hampshire go first is money. The two states are small enough that good candidates without deep pockets still have a viable shot at making their case to voters. Candidates can literally go door to door, and can meet voters in small, intimate,
and inexpensive settings like schools, churches, and coffee shops. They can gain exposure and build a campaign without spending millions of dollars on ads.
If we started with California or Florida instead, for example, only the two or three establishment candidates with big war chests would have any chance at all. It wouldn't be practical to meet any significant percentage of voters in person. Instead, it would be a battle of expensive advertising campaigns.
