But can she walk it?
As the campaign for the Democratic presidential nomination has drawn on, it has typically become even more contentious and even more divisive.
Hillary Clinton finally spoke out on that particular topic today, as she noted that she would prefer her supporters vote for Barack Obama should he secure the Democrat nomination.
"Anybody who has ever voted for me or voted for Barack has much more in common in terms of what we want to see happen in our country and in the world with the other than they do with John McCain," Clinton announced.
"I'm going to work my heart out for whoever our nominee is -- obviously I'm still hoping to be that nominee, but I'm going to do everything I can to make sure that anyone who supported me... understands what a grave error it would be not to vote for Senator Obama," she added.
Yesterday, Clinton won the West Virginia primary in a 41-point victory dismissed by some as irrelevant -- a win Clinton desperately needed to justify staying in the race.
But with the vast majority of observers insisting that the race has largely been decided in Obama's favour, one has to wonder if Clinton has finally found the high road so she walk it, or so she can use it to travel to a Vice Presidential nomination.
After all, one remembers some of Clinton's recent rhetoric, and remembers how low Clinton was willing to stoop in order to get -- or at least maintain -- an edge over Obama in West Virginia.
But if Clinton is resolutely determined to actually walk the high road, the prospects of a Democrat president in 2008 may have just brightened significantly, as those helping to turn the lights down on that possibility -- entrenched Clinton and Obama supporters unwilling to vote for the other candidate -- may have just been given cause to think twice before voting for John McCain.
