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.

In addition to Romney and Santorum, Ron Paul and Newt Gingrich both matched or surpassed the 13 percent level of support that John McCain — on his way to winning the Republican nomination — received in Iowa in 2008.

Lastly, Romney failed to equal the 25.2 percent share of the vote that he received in Iowa in 2008, finishing with 24.6 percent support this time around.
