Joe Lieberman tells The Miami Herald's Marc Caputo that Marco Rubio is deeper than he's often given credit for.
“Marco’s not a show horse.... He’s a workhorse.”
Considering their shared hawkishness, that's not a terrible surprise.
What's more notable is John Kerry's praise.
“A lot of the colleagues around here, obviously, are interested in substance and interested in people who do the work and are not impressed by people who are prone to play the political end of something and hold a press conference and not do the work,” Kerry said.
“They want to see someone buckle down and learn the ropes. And I think he’s clearly been doing that in a very positive way.”
Now... here's something interesting.
If you mosey on over to Rubio's official Senate site, you'll find a number of photo galleries.
Of the nine galleries presented, seven are related to the military, border patrol, or veterans' affairs.
Clearly, Rubio's determined to become a major voice on foreign policy and wants to be identified as such.
There's a substantive component to that, but probably a political one, as well.
One of the greatest obstacles standing in the way of a young VP or presidential candidate is the perception that foreign policy requires a more seasoned, older hand, and that perception could hurt Rubio's push for a quick national rise.
But he seems to be taking both big and small steps to assuage those concerns.
