For all the reasons we’ve talked about many times, national horse-race polls tend to be of limited predictive value. As is the case in the general election, the nominating process is a state-by-state affair. A candidate can soar in national polls, but if he or she is trailing where it counts, those national leads are meaningless (see Giuliani, Rudy, circa 2007).
That said, national polls are interesting for highlighting broader, general trends. And right now, the trend seems to be moving in one direction. Throughout the fall and early winter, Hillary Clinton’s national lead was around 20 points. Now, the race for the Democratic nomination is in such flux, some polls shows the lead evaporating. CNN just released its newest national poll, for example, which shows Barack Obama catching up to Clinton for the first time.
Obama, who trounced Clinton in January’s South Carolina primary, garnered 49 percent of registered Democrats in Monday’s poll, while Clinton trailed by just three points, a gap well within the survey’s 4.5 percentage point margin of error.
“Coming out of his overwhelming victory in South Carolina and followed quickly by his Kennedy family endorsements, Obama clearly has the momentum in this campaign,” said Bill Schneider, CNN’s senior political analyst. […]
The poll is consistent with other national surveys during the past few days. A CNN averaging of five national polls conducted in the last few days — a “poll of polls” — puts Clinton at 45 percent and Obama at 43 percent. Those five surveys were done by CNN/Opinion Research Corp., Gallup, Pew, ABC and CBS.
As for the general election match-ups — a constant source of debate between the two Democratic camps — the CNN poll shows Clinton leading McCain by three (50% to 47%), while Obama leads McCain by eight (52% to 44%).
Of course, CNN’s is just one poll, but there appears to be a fairly significant shift underway nationally.
* The latest WaPo/ABC poll shows Clinton’s lead down to four points, 47% to 43%. (The same poll found that McCain beats Clinton by three points, 49% to 46%, while Obama beats McCain by the exact same margin, 49% to 46%.)
* The latest CBS/NYT poll found Obama and Clinton tied nationally at 41% each.
* The Pew Forum’s poll gives Clinton her largest lead of any recent national poll — 46% to 38% — though the eight-point margin is down from 15 points a month ago.
* The new USAT/Gallup poll shows Clinton’s lead down to one, 45% to 44%.
It looks like a race that will go on for quite a while.
And what of the Republicans? Well, it’s actually kind of boring.
In the battle for the GOP nomination, McCain has the backing of 44 percent of registered Republicans, while former Massachusetts Gov. Mitt Romney received 29 percent, former Arkansas Gov. Mike Huckabee got 18 percent and Rep. Ron Paul of Texas won 6 percent.
McCain took the top spot in most national surveys of Republican voters after his January 8 victory in the New Hampshire primary. […]
CNN’s “poll of polls” of the Republican race puts McCain at 45 percent compared with 24 percent for Romney.
It’s not enough that the Republican candidates are duller and less interesting than the Dems, but now the Republicans’ race is duller and less interesting, too.
