Here’s an interesting tidbit to think about on Election Day: Using Polidata projections for the 2010 census, and electoral distribution from the 2004 presidential election, Republican states will grow (in both congressional seats and number of electors to the Electoral College) while Democrat-leaning states will shrink. As analyst and columnist Michael Barone has pointed out, the demographic trends don’t prevent President Barack Obama from being reelected in 2012—

but they would make it marginally more difficult. Demography, modestly, favors the Republicans, and more than modestly over the long haul.

The demographic trend is more significant in light of what Gallup and others are finding regarding individual Americans’ shift to identifying themselves more prevalently as conservative. But as E.J. Dionne has pointed out, “There is a debate over what these ideological labels actually mean to voters.”
