A little more seriously: I think the biggest thing keeping good people from public office these days is all the bullshit that they have to go through in a protracted campaign. I think this is one of the reasons we end up with such poor choices available to us in any Presidential Election. OTOH, I think that given the opportunity to jump in with only a few weeks left and not have to go through all the BS, that there would be a much larger pool of guys who would take the chance/opportunity. If they told Lautenburg 5 months before the election, he might have said "no". But this was a "no lose" proposition for him ( if he loses, he simply says "what did you expect ? I only had a few weeks to run" ).
