The weakness of Lind's thesis assumes that once the dust settles, there must yet remain only two parties.
First, I sense that the dust is not going to settle much after November.
Second, the President-elect will suffer the worst support of any President since Gerald Ford, or maybe Hoover, because clearly there are four strong, distinct strains presenting their cases in the current campaign.
The theory behind our "great two-party system" is that the winner commands a majority of Americans. Twisted theory. When 28% of the electorate participates, then only 15% of Americans have chosen the president. When candidates get independent voters off their duffs, they raise the voter participation level. Which, while I haven't totaled the votes cast and can't possibly know the votes denied or prohibited in current campaign, seems to have happened this season.
Lind also reads the younger generation wrongly. Especially when he needs to sort them into races and locale. What I see of this group is increased interracial marriage, high mobility, and the abandonment of political and social borders. I'm puzzled by the means and speeds of their associations, but I trust they're going to figure out the right way to shape the future. Guys like me just need to keep smiling as they fly by-- and hope they won't forget that we gave it our best try in our own time.
