How will Ted Kennedy's endorsement affect the presidential race? The debate is already well underway. Skeptics note that endorsements don't have the same weight they did a few decades ago, when more voters took their cues from party leaders. Al Gore's endorsement of Howard Dean four years ago certainly didn't deliver the nomination.
But Kennedy's progressive record on economic issues, not to mention his family name, might give him unusual clout with older, working-class white voters -- ones who, until now, have strongly preferred Hillary Clinton. Kennedy is also said to be popular with Latinos, thanks in part to his history of championing liberal immigration reforms and to Robert Kennedy's early support of Cesar Chavez.
This is where the timing of Kennedy's announcement -- and peculiar dynamics of this race -- could prove critical. Latinos, who have strongly favored Clinton so far, are well-represented in the big states voting on February 5. And while Kennedy's endorsement alone surely isn't enough to swing a whole state like New Jersey or California, it might be enough to shift enough votes to change delegate counts -- which is what really matters at this point.
Remember, Democratic primaries aren't winner-take-all. Even if Clinton wins more votes in the biggest coastal states, a strong second-place showing by Obama in those places -- combined with winnings in Illinois and other interior states -- could give him the majority of the day's delegates. (Or at least keep the count pretty close.)
Of course, all of that is just guesswork, based on polling numbers that may not be accurate and assumptions about voter attitudes that may not be correct.
