What else can Hillary Clinton’s come-from-behind victory–and John Edwards’s dismal third-place showing–in New Hampshire last night mean for the former, one-term Senator from North Carolina other than that he must now drop out of the race? This might seem counterintuitive in the lead up to the South Carolina Democratic primary, to be held on January 26th, where Edwards is presumed to have favor with voters because it’s his own neighborhood. But the latest poll from South Carolina shows Barack Obama with 42 percent, Clinton with 30 percent and Edwards with a dismal 14 percent. The poll was published Monday, before Clinton’s resounding New Hampshire win, so it’s probable that she’ll pick up even more support from Obama, and possibly Edwards as well. To avoid a crushing, embarassing coda to his already lackluster political career, Edwards should probably just call it quits now.
