ATLANTA — Republicans crowed in 2004 that freshly re-elected President George W. Bush had established a "permanent governing majority" for the GOP. Eight years later, Democrats were touting the enduring power of the "Obama coalition" to keep their party in the White House. But Democrats couldn't sustain that coalition for this year's midterm elections, leading to Republican gains in Congress, governorships and state legislatures nationwide. "The notion of demographics as destiny is overblown," said Republican pollster and media strategist Wes Anderson.
