When the Republican National Convention finally gets underway today here in Tampa, it will renew a civil war that's been raging — off and on — for more than a century.

You may already have made a mental note as to where you were when you heard the Supreme Court had upheld the health care law known as Obamacare. It's one of those moments that become touchstones of our memory, personal connections to the history we have witnessed in our lifetimes.

The Supreme Court may not be the source of such moments very often, but when its rulings reach this level of our awareness, they alter the course of our lives.

For weeks now, we in the news business have been telling you how much the Scott Walker recall election in Wisconsin matters to the country as a whole.

Gov. Scott Walker beat back a recall attempt in Wisconsin on Tuesday by doing what he had to do: turning out huge majorities in the Republican enclaves of the state — especially in its eastern half near Lake Michigan.

In the end, Walker wound up with about 53 percent of the vote, about 1 percentage point better than he had in winning the governorship the first time in November 2010.

The latest variant of the presidential election parlor game we call "What Were They Thinking?" asks why Mitt Romney chose this moment in his quest for the White House to become involved with Donald Trump.

Here's a contrarian guess by way of an answer: populism. Bear with me for a moment of explanation.

Back before the conflagration that was World War II, some of Europe's great powers engaged in a surrogate struggle by arming the warring factions in the Spanish Civil War. It was a great way to test their latest weapons and tactics.

Here in our country and in our time, the role of Spain is being played by the state of Wisconsin, where a political civil war has raged for nearly 18 months — presaging the fierce national politics of this presidential year.

Watch Wisconsin over the next four weeks, and you will see where we are headed as a nation in the months ahead.

It is time for the much-winnowed field of Republican presidential contenders to shrink a little further. It is time for Newt Gingrich to bid adieu and wrap up his bid for the nomination.

Rick Santorum, who won the Alabama and Mississippi primaries on Tuesday, has proven himself the conservatives' favored alternative to front-runner Mitt Romney. He did this by winning the voters who mattered most in the deep-dyed red states of Alabama and Mississippi, the white evangelical "born again" voters who cast more than two-thirds of the vote in each state.

By embracing Newt Gingrich in its primary, the South Carolina GOP has risked its remarkable record of success at picking the party's eventual nominee for president.

It's been quite a run. Beginning with its primary in 1980, when it chose Ronald Reagan, South Carolina has voted first among Southern states. And the Palmetto State's choice has gone on to dominate the other Southern states and lock up the nomination in short order. That happened eight times in a row, counting incumbent renominations.

As Mount Washington calmly reigns over much of New Hampshire's geography, Mount Romney smiles down on the last day before the state holds the nation's first presidential primary.

The front-running former governor of neighboring Massachusetts spent the day getting chummy with crowds in Nashua and Hudson and Bedford, reciting his favorite lines from "America the Beautiful" and engaging in other behaviors just as risky. He came out in favor of free enterprise and job creation and got really cross with the Chinese for currency manipulation and intellectual property theft.

At last, the rivals who were supposed to savage front-runner Mitt Romney in the final weekend before Tuesday's primary in New Hampshire got down to business.

In the opening minutes of their debate Sunday on NBC's Meet the Press, several of those chasing Romney in the polls let fly the roundhouse punches they'd been pulling through weeks and months of TV debates.

Once more, the great media consensus was confounded. Saturday night's debate at St. Anselm's College in Manchester, N.H., produced another battle among half a dozen presidential contenders, much like a dozen before it. Front-runner Mitt Romney was neither knocked out nor even knocked down. He was scarcely even knocked around.

Once again, the evening ended with the bruises pretty equally distributed among the contestants. And with the New Hampshire primary bearing down on Tuesday, virtually no time remains for Romney's rivals to bring him down.
