A brokered convention?

Drudge has this for an Iowa-morning-after headline:
MITT 30,015
RICK 30,007

The Associated Press reports the results:
"Returns from all 1,774 precincts showed both Romney with 24.55 percent support and Santorum with 24.54 percent. Texas Rep. Ron Paul drew 21.5 percent of the votes."

Something was brought up last month. I saw it on The Most Important News and then The Truth Wins on US News & World Report. It is about a "brokered convention,"

"Sarah Palin or Jeb Bush could still win the Republican nomination in 2012 and become the next president of the United States. Really. In fact, Paul Ryan, Jim DeMint, Mitch Daniels and Chris Christie still have a chance too. How could this be? It is called a "brokered convention", and it has become a very real possibility for the Republican Party. In fact, Paul Ryan, Jim DeMint, Mitch Daniels and Chris Christie still have a chance too. How could this be? Well, it has now become clear that there is a very real chance that no Republican candidate will hold a majority of the delegates by the time the Republican convention rolls around. If that happens, that would mean that we would have the first "brokered convention" in decades. The truth is that the Republican establishment does not want this, but they are also scared to death of having someone like Newt Gingrich or Ron Paul as the nominee. So exactly what is a brokered convention?"

Wikipedia says of the process:

"A brokered convention is a situation in United States politics in which there are not enough delegates 'won' during the presidential primary and caucus elections for a single candidate to have a pre-existing majority, during the first official vote for a political party's presidential-candidate at its nominating convention. Once the first ballot, or vote, has occurred, and no candidate has a majority of the delegates' votes, the convention is then considered brokered; thereafter, the nomination is decided through a process of alternating political horse-trading, and additional re-votes. In this circumstance, all regular delegates (who, previously, were pledged to the candidate who had won their respective state's primary or caucus election) are "released," and are able to switch their allegiance to a different candidate before the next round of balloting. It is hoped that this 'freedom' will result in a re-vote resulting in a clear majority of delegates for one candidate."
