After meriting a couple of momentary mentions during the primary season, the “Keating Five” scandal — the 1980s savings-and-loan debacle that Sen. John McCain once called the biggest mistake of his career — now has surfaced again in all its ugly glory. As global financial stability today teeters on the edge of collapse, those looking for reasons leading to the present meltdown should take a close look at the Republican presidential candidate’s regulatory philosophy over his quarter-century in Congress and his role in the infamous S&L scandal.

CBS News this week continued airing its ongoing series of interview segments with the 2008 presidential and vice-presidential candidates, whose answers when asked the same questions revealed much about their respective vision for governing the country. Viewers have a question of their own to answer: “How do these candidates’ answers match their past behavior — both during their careers and also in the way they have conducted their campaigns this year?” The three vice-presidential clips aired Wednesday-Friday. For those who did not view the earlier Sept. 18 and 24 segments featuring the two presidential contenders, they also are posted here.
