Often, the answer is yes. And if Barack Obama and Mitt Romney win the Democratic and Republican caucuses respectively, the biggest spenders will be the biggest winners. But what if John Edwards prevails over Obama and Hillary Clinton, despite having spent far less in Iowa than either of his rivals? Even more shocking proof that money does not always buy voter love would be a victory by Mike Huckabee over Romney in the GOP contest. Romney has outspent Huckabee by 5-to-1 on ads in Iowa, and by a much larger margin overall. And yet Huckabee and Romney were in a dead heat in most of the final polls going into today's caucuses.
