There are many reasons to be optimistic about environmental improvement.

Last week I wrote about the standings in the presidential race and said it looked like a long, hard slog through about a dozen clearly identified target states, much like the contests in 2000 and 2004. Call it the 2000/2004 long, hard slog scenario.

Every federal official has an obligation to act in line with the Constitution as he or she understands it. And that doesn't necessarily mean obeying Supreme Court decisions.

Last week’s election indicates that the GOP marriage with the white working class is on the rocks. That’s bad news, since the epic Republican landslide in 2010 was fueled by record-high margins among these voters.

Republicans and Democrats alike have learned that invoking Ronald Reagan won't get them as far as it used to.

This week's historic Republican landslide is due to a massive swing among white working-class independents in rural and exurban areas, rather than an enthusiasm gap between Republican and Democratic supporters, as the party predicted.

People are misrepresenting Reagan's necessary compromises while in office, to incorrectly associate him with having a liberal agenda.

The House and Senate elections of 2010 have similarities with the elections of 1980, when many Republicans owed their election to populist reaction against the Panama Canal Treaties.
