Random aside, but "all politics is local" was popularized by Speaker of the House Tip O'Neill, the longest continuous Speaker in House history (5 terms, no interruptions!).
GBH is 1/2 way through a podcast about Boston's Big Dig, which started while Tip was Speaker, and resulted in an enormous tunnel named after the man who shepherded its funding through Congress. It's a great listen, and, so far, is abundant evidence that all politics is, indeed, local. Thanks for the tip, Tip!
