With former Sen. Fred Thompson's official declaration of his candidacy, the race for the Republican presidential nomination has now assumed the shape that seems likely to characterize it right down to the finish line. Conceivably some new and unexpected contender could still enter the contest and win it, as Wendell Willkie did in 1940, but the odds against such a development are high.
Some observers, noting that the national political conventions won't be held until the late summer of 2008, argue that there is still time for a surprise. But by advancing the dates of many of the most important primaries to early next year, the parties have dramatically shortened the time actually available. Within five months -- by early February -- we will almost certainly know the identity of the Republican and Democratic candidates who will be officially nominated next summer. (And that, incidentally, will raise an interesting question for both of them: Just how will they maintain their momentum from early February to Election Day, Nov. 4?)
In the case of the Republicans, the striking fact is that the field of serious contenders is still so large. At this point, it is certainly possible that any one of at least five men -- Sen. John McCain of Arizona; Thompson of Tennessee; former Gov. Mitt Romney of Massachusetts; former Gov. Mike Huckabee of Arkansas, and former Mayor Rudy Giuliani of New York City -- could easily win the nomination. (There are a few other possibilities as well, witness the recent "debate" among Republican aspirants, but those five are certainly the standouts at the moment.)
The remarkable thing is that not one of these men has established a truly formidable lead. Giuliani has held onto the top spot in most national polls of Republican primary voters, but this amounts in most cases to about 30 percent, with various rivals close behind; it is certainly not enough of a margin to make him a prohibitive favorite. Romney, interestingly, leads the field in Iowa and New Hampshire, which are both key states with primaries early in the year, and victories there (if he achieves them) would give him an important boost.
