Looking at this graph of party identification by age in the U.S., I was not surprised to find 40-year-olds like me in the best cohort for Republicans. My peers vaguely remember the oil shocks and high inflation of the 1970s, and then came of age during Ronald Reagan’s “morning in America.” In those days, many young people proudly identified with the Republican Party. As they grew older, lots of them continued to vote that way.

Americans who were growing up during the presidencies of Bill Clinton and George W. Bush are much more likely to call themselves Democrats or independents than Republicans. They also voted Democratic by large margins in the 2006 and 2008 general elections. If Republicans can’t figure out a way to compete with this group of voters, Democrats will have a built-in advantage for decades.

Fixing this problem won’t be easy for the GOP and may even be impossible, for reasons I discuss after the jump.
