The Obama-Bloomberg breakfast this morning raises the obvious thought: isn't Obama-Bloomberg a logical 2008 Democratic ticket? Bloomberg brings executive experience, maturity, resources, and some bipartisanship (he is a nominal Republican) to an Obama candidacy, while being acceptable on fundamental issues to the Democratic base. It would be an interesting campaign, in accord with our interesting times, to have both parties running "national unity" tickets - Obama-Bloomberg vs., say, Thompson-Lieberman.
