Tomorrow, the 40th Republican National Convention assembles in hurricane-threatened Tampa, and eight days later the 46th Democratic National Convention will assemble in presumably non-hurricane-threatened Charlotte. Thousands of delegates, many thousands more press personnel and even more political enthusiasts will be on hand.
Vendors will sell political buttons to collectors (does anyone wear them any more?) and party volunteers will hand out bumper stickers (though I haven't seen many on cars anywhere this year). Party fatcats will attend elegantly catered receptions and those lower on the political ladder will buy hot dogs from vendors or sample local cuisine (Cuban food in Tampa's Ybor City; North Carolina barbecue).
The conventions will adopt rules that don't matter (except possibly on delegate selection), adjudge credentials with utter predictability and adopt platforms that bind no one. And, of course, delegates will officially nominate Mitt Romney and Paul Ryan in Tampa and Barack Obama and Joe Biden in Charlotte.
People (and the federal government) will spend very large sums of money on all this. Many will ask why we still have national conventions at all.
They are a gift, an unwanted gift for some, from history. The national convention was originated by the long-departed Anti-Masonic Party in 1831 and copied by Andrew Jackson's Democrats in 1832. After the Republican party was formed in 1854, it followed suit with a national convention in 1856.
Until the 1960s, the national convention was a communications medium. Political leaders in the various states seldom met each other, outside of sessions of Congress, during the four years between presidential elections.
Men did business in written form well into the 1960s: they spent their days reading their correspondence, dictating replies and proofreading and signing their letters. Long-distance telephone calls were unusual; direct distance dialing was introduced only in the 1950s.
People ordinarily didn't put in writing their bottom line negotiating position. Recipients sometimes ignored the command to "burn this letter." Better to wait until you could meet in person, in the convention city.
As a result, even the shrewdest politicians didn't know who had how many votes until the convention roll call was conducted. Campaign managers would hold back votes on early ballots to show momentum later. "Favorite son" candidates with support from home state delegations would wait for real contenders to bid for their support.
So there was suspense and drama to the proceedings. In 1960, John Kennedy got his majority for the Democratic nomination from Wyoming, the last state on the roll call. It was not until 1968 that the first media delegate count was conducted by Martin Plissner of CBS News.
The media delegate counts proved correct in the close 1976 Republican race between Gerald Ford and Ronald Reagan. At which point the conventions started to take on their current form, as an advertisement for the presidential nominee and, perhaps secondarily, his party.
Sometimes things don't work out. Edward Kennedy avoided grasping Jimmy Carter's hand on the podium in New York in 1980 and Patrick Buchanan arguably overshadowed George H. W. Bush in Houston in 1992. But mostly things go according to script.
The Romney people have theirs prepared. Monday night is "we can do better," with the campaign trying to persuade one of the three broadcast networks to carry Ann Romney's speech. Tuesday is "we built that," with a Ron Paul video -- Hurricane Isaac permitting.
Wednesday is "the middle class agenda," with promises of more jobs and take home pay. And Thursday, always the climactic night, is "we believe in America," with testimony about Romney's work in the Mormon Church and in the Salt Lake City Olympics and, of course, the nominee's acceptance speech.
The Romneyites are proud of their 3D high resolution videoscreens (in the old days delegates watched the tiny distant speakers), the podium inspired by Frank Lloyd Wright (a Wisconsin native, like Paul Ryan), and their efforts to interact with social media like Facebook and Twitter.
But, of course, it matters much more how the nominees, Paul Ryan and especially Mitt Romney, come across. That's the whole point of still holding national conventions.
Some pundits lament the demise of the old conventions. But they couldn't be revived without banning long-distance telephone, the Internet, and jet travel.
Contemporary conventions give parties a chance to showcase their nominees. As in much of our politics, an antique form still performs a useful function.
