I write this for two reasons, which I will elaborate below. One, it is becoming likely that Kerry is going to win the electoral college. Admittedly
likely, not defintive, but his odds are over 50% in this regard right now. However, I'm much less sure about the popular vote, which truly is up in the air.
If Kerry is to win the national popular vote, his margin is going to come from huge turnouts in cities like San Francisco, LA, Oakland, Chicago, Seattle, Philadelphia, New York, Detroit, Cleveland, Milwaukee, Boston, Portland, and even in "red state blue oases" like Austin, Atlanta, and parts of Houston, Dallas, and so forth. At this point, if you are living somewhere like this and are wondering where to spend the next week (or some days of the next week), considering staying put and hunting for infrequent Democratic voters in these places. You are not useless in a "safe" part of the country: in fact, you're efforts in some of the bluest (and reddest) states in the union could be vital to Kerry's ability to govern with a mandate.
Relatedly, my second reason why a "mad dash" from, say, California to Nevada or Oregon, or New York to Ohio may not be the best of ideas is the "perfect storm" scenario: where a bunch of overeager, undertrained out-of-towners descend on an area that is already well-covered by pro-Kerry GOTV operations, turning off likely voters through overkill. Frankly, most swing areas are blanketed, and as mcjoan noted in a diary about Oregon a week or two ago, these efforts are maybe even too much. We don't need San Franciscans in Las Vegas at this point. We need your vital efforts in San Francisco (and LA, and NYC, and Boston, and Chicago, and Seattle, and Portland, and Detroit, and Minneapolis, and so on) at this point to ensure Kerry wins the popular vote.
