Yesterday, I posed five questions about the Iowa caucuses, and the answers are now in. Mitt Romney set a new all-time record for the lowest winning share of the vote (for either party) in the Iowa caucuses — 25 percent — one point lower than Bob Dole’s 26 percent level of support in 1996. That’s well below the 31 percent tally that every previous Republican winner except for Dole had achieved. 

Romney did make good on his prediction that he was going to win the Iowa caucuses, although he certainly cut it close — beating Rick Santorum by less than 1 vote for every 15,000 votes cast.
