Interesting analysis of the election results from Karl Rove in yesterday's WSJ. After noting the big increase in minority turnout for Obama he notes the big story on the Republican side--the decline in turnout about Republican voters:

Then there were those who didn't show up. There were 4.1 million fewer Republicans voting this year than in 2004. Some missing Republicans had turned independent or Democratic for this election. But most simply stayed home. Ironically for a campaign that featured probably the last Vietnam veteran to run for president, 2.7 million fewer veterans voted. There were also 4.1 million fewer voters who attend religious services more than once a week. Americans aren't suddenly going to church less; something was missing from the campaign to draw out the more religiously observant.

In a sign Mr. Obama's victory may have been more personal than partisan or philosophical, Democrats picked up just 10 state senate seats (out of 1,971) and 94 state house seats (out of 5,411). By comparison, when Ronald Reagan beat Jimmy Carter in 1980, Republicans picked up 112 state senate seats (out of 1,981) and 190 state house seats (out of 5,501).

In the states this year, five chambers shifted from Republican to Democrats, while four shifted from either tied or Democratic control to Republican control. In the South, Mr. Obama had "reverse coattails." Republicans gained legislative seats across the region. In Tennessee both the house and senate now have GOP majorities for the first time since the Civil War.

Republicans staying home thus squares the circle that Ilya has noted--namely the apparent increase in turnout among young voters and minorities while the absence of a noticeable increase in turnout overall.
