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.
In the past two months, Senator Barack Obama has built a commanding coalition among Democratic voters, with especially strong support among men, and is now viewed by most Democrats as the candidate best able to beat Senator John McCain in the general election, according to the latest New York Times/CBS News Poll.
After 40 Democratic primaries and caucuses, capped by a winning streak in 11 contests over the last two weeks, Mr. Obama has made substantial gains across most major demographic groups in the Democratic Party, including men and women, liberals and moderates, higher and lower income voters, and those with and without college degrees.
The NYT emphasizes that there are “signs of vulernability” for Obama, including what the Times refers to as “a striking gender gap”: Obama is “backed by two-thirds of the Democratic men and 45 percent of the women, who are equally divided in their support between the two candidates.” (When one candidate has a clear majority of men, and a near majority of women, I’m not sure if I’d necessarily call this a “sign of vulnerability.”)
More to the point, good news for the Clinton campaign is elusive. The New York senator now trails Obama among Dems nationwide, 54% to 38%. What’s more, Obama is gaining with groups he was struggling with — his support among lower-income households has gone from 35% to 48% since December, support among moderates has gone from 29% to 59%, and support among white women has gone from 19% to 40%.
As for electability, nearly six in 10 Dems said Obama had the best chance of beating McCain in November.
A new national poll from USA Today/Gallup offered similar results.
The sense that Democratic presidential candidate Barack Obama is more electable than Hillary Rodham Clinton has trumped concerns about whether he has the experience necessary to be a good president, a new USA TODAY/Gallup Poll finds.
The air of inevitability that once surrounded Clinton has shifted to the Illinois senator, now seen by seven in 10 Americans as the likely Democratic nominee.
In a poll taken Thursday through Sunday, Democrats and Democratic-leaning independents say by 2-1 that Obama has the better chance of beating the Republican in November. Republicans agree: By more than 3-1, they say likely GOP nominee John McCain has a better chance of beating Clinton than Obama. […]
In a general-election matchup among registered voters, Obama leads McCain by 4 percentage points, 49%-45%; McCain leads Clinton 49%-47%. McCain does better among likely voters, edging Clinton by 4 points, Obama by 1.
Head to head, Obama now leads Clinton nationally among Dems, 51% to 39% — the first double-digit lead Obama has enjoyed since the process began early last year.
Clinton fans hoping for some poll solace might be slightly more encouraged by the results of a new AP/Ipsos poll released last night, which shows Obama with a national lead over Clinton, but by a much smaller three-point margin, 46% to 43%. As for the general election match-ups, Clinton leads McCain nationally by five (46% to 41%), while Obama leads McCain nationally by nine (48% to 39%).
