The latest Chicago School piece in The New Republic by Daniel Drezner argues that Howard Dean is about as credible as his fellow Democratic candidates on national defense, although Dean does share Dick Gephardt’s isolationist views on trade. (A number of relevant links are at Dan’s blog.)

Meanwhile, James Joyner thinks the combination of frontloading and proportional delegate allocation may lead to a brokered convention. Since nobody’s going to completely run out of money before the primaries are effectively over, there is a fair chance that no candidate will get a majority of the delegates; if any candidates are going to drop out, they’re probably going to do it before Iowa. And given that the presidential primaries often are both standalone (with no other races on the ballot) and open, there’s a reasonable chance there will be significant cross-over voting among Republicans, which may help fringe candidates and those who may be perceived as too liberal to win the general election—Sharpton and Dean could quite possibly pick up a large chunk of delegates in the South with a combination of black votes and Republican crossover voters acting as “spoilers.”
