Nonetheless, there is nothing inexorable about the current Obama slide. The race remains 50-50. Republican demoralization after a primary campaign that blew the political equivalent of a seven-run lead has now given way to Democratic demoralization at the squandering of their subsequent ­post-primary advantage.

What remains is a solid, stolid, gaffe-prone challenger for whom conservatism is a second language vs. an incumbent with a record he cannot run on and signature policies — Obamacare, the stimulus, cap-and-trade — he hardly dare mention.

A quite dispiriting spectacle. And more than a bit confusing. Why, just this week the estimable Jeb Bush averred that the Republican Party had become so rigidly right-wing that today it couldn’t even nominate Ronald Reagan.

Huh? It’s about to nominate Mitt Romney, who lives a good 14 nautical miles to the left of Ronald Reagan.
