Hillary Clinton’s attempt to impersonate a Nascar-lovin’, gun-totin’, economist-bashin’ populist went bust: Asked which candidate most “shares your values,” voters in both North Carolina and Indiana exit polls opted instead for the elite and condescending arugula-eater. Bill Clinton’s small-town barnstorming tour, hailed as a revival of old-time Bubba bonhomie, proved to be yet another sabotage of his wife, whipping up false expectations for her disastrous showing in North Carolina. Barack Obama’s final, undercaffeinated debate performance, not to mention the Rev. Jeremiah Wright’s attempted character assassination, failed to slow his inexorable path to the Democratic nomination.
