The Klobuchar buzz may be less about Iowa -- associates of hers say this speech is much ado about very little since Klobuchar travels to Iowa often -- and more about the bench of Democratic officials and where they're headed in the post-Obama era.
Several others must navigate their future political trajectories with the looming presence of a Clinton presidential run. They include Maryland Gov. Martin O'Malley, who put his thumb on the scale last week in New Jersey's Democratic primary for U.S. Senate by backing another rising star, Newark, N.J., Mayor Cory Booker; Sen. Kirsten Gillibrand, another Senate newbie who has impressed with her work ethic and aptitude for retail politics; and Biden.
For some of the lesser known Democrats, raising a national profile is half the battle.
Gillibrand took a step to raise hers by inking a book deal with Ballantine Bantam Dell. The book is slated to be released in 2014 -- a formula followed by Clinton and Obama before their presidential runs. And she has defied Senate leadership with a push to take military sexual assault cases out of the military chain of command.
Both Gillibrand, 46, and Klobuchar, 53, are relatively young, leaving them plenty of time for the chattering class to speculate on their political futures.
"She's the kind of person on the national stage we'll wonder about and will wonder about for a long time," noted a longtime friend of Klobuchar's.
