John Eastman correctly points out the difficulty for Mondale with the absentee ballots, and I fully agree that there is legal action on the horizon. I would only add that the delay in announcing the candidacy may be more politically than legally strategic. Those who watched the talk shows this weekend noted that liberal commentators got free reign to praise Mondale, while any comments about his record of tax increases were quickly swatted down, claiming that it was improper to talk about such things before "we have had a chance to mourn" and before Mondale formally announces his candidacy. It now appears that Mondale will announce his decision to run after after the Wellstone memorial service tomorrow. In addition to showing some actual respect for the deceased, it also gives Mondale a maximum opportunity for criticism-free campaigning. Essentially, the media and liberal analysts get a few days to talk about what a great choice Mondale is, while shouting SHAME to anyone who would politicize the moment by talking about issues.
This is not to say that I disagree with John--to the contrary I think he is right to point out that legal calculations are impacting the timing--rather I simply add these political calculations to the timing question.
