Via Iowa Independent:

Former U.S. Sen. Mike Gravel, D-Alaska, is running, at age 76 and after years out of the public arena, the longest of long-shot candidacies for the presidency.

With his colorful confrontations of other Democratic candidates during a recent debate in South Carolina, Gravel has generated some buzz in the liberal blogosphere — and he even earned some time with MSNBC’s Chris Matthews.

Gravel conducted a one-on-one, 45 minute conversation with Iowa Independent fellow Douglas Burns.

Iowa Independent: When I watched the debate the other night, and don’t take this the wrong way, but you seem awfully angry for a 76-year-old. Why are you so angry?
