Des Moines, Iowa (CNN) - After a year when the Republican presidential race became defined by debates and cable news chatter instead of retail politics and town hall meetings, Iowa seems primed, in the end, to reward the candidates who did things the old-fashioned way.
Three Republican candidates - Ron Paul, Mitt Romney and Rick Santorum - are on the cusp of grabbing a coveted top-three finish in Iowa, the leadoff caucus state, which rarely picks presidents but usually find a way to whittle down the field of candidates.
A Des Moines Register poll of likely caucus-goers released late Saturday found Romney clinging to a narrow lead with 24%, followed by Paul at 22% and Santorum gaining steam at 15%.
