Some historical perspective, about polls, as I expect there to be some up-and-downs for us.
In August 1988, Michael Dukakis was leading George Bush (the first George Bush) in the polls by landslide margins.
In November 1988, George Bush won the presidency in the third Republican landslide in a row.
Sometime in mid-1968, Richard Nixon was leading in the polls by supersupersuperlandslide margins.
In November 1968, Richard Nixon barely beat out Hubert Humphrey by a razor-thin margin.....although one has to remember the big city machines created all these "votes" for the Democrat candidate, and so the margin was probably in reality not that narrow.
The polls are going to go up-and-down for us (and for the primitives), and it shouldn't be a great concern until a week or so before November 2008, where they're at, and of course one has to keep his eyes on Republican-run bastions such as Chicago and Detroit and Seattle and Lost Angeles and Pittsburgh and New Orleans and Miami and Philadelphia and Kansas City and Seattle and Milwaukee and Cleveland and Buffalo and Baltimore and St. Louis and &c., &c., &c., to be sure the Republican machines there aren't too productive at creating "votes."
