Two honest right-leaning writers, libertarian Matt Welch and conservative Tim Carney, agree that had John McCain been elected in 2008, domestic policy largely look the way it does now, healthcare excepted, and that our foreign policy would likely be far worse. They're also concerned, as the Dish is, that if Republicans retake the House, especially under current leadership, the K Street faction will coopt them, or else they'll take up social issues because the real fiscal choices are way too hard for them to win re-election on.
If more voices on the right were similarly skeptical of folks on their own side, there might be enough accountability to advance small government ends through a GOP controlled Congress. More power to them. Unfortunately, the most trusted voices on the right -- people like Limbaugh, Hannity, Palin, Levin, and Beck -- are either partisan hacks, ideologues who abandon small government principles whenever the word terrorism is uttered, or... well, who can say what Glenn Beck is?
