Gallup Looks at Age Dynamics in the General Election

Gallup has a new poll up looking at various demographic dynamics in the Obama-McCain general election matchup. Here's what they're showing for the different age demographics/generations:

There are two interesting things to note here:

1. As DemFromCT notes, Gen X appears to be losing it's conservative voting habits and turning to the left. This supports similar data reported by PEW earlier this year, and is super bad news for Republicans. Gen X - particularly the older members - have long been one of their most reliable voting demographics. In 2004, Bush won 30 - 44 year olds (Gen X and younger Boomers) 53 - 46%.
2. Obama's advantage among Millennials echoes what we saw in 2006 when young voters chose Democrats 60 - 38%. In 2004, Kerry won young voters by a much slimmer 54 - 45%, and young voters were 17% of the electorate.

If Gen X votes Democratic, or splits it's vote in November, and if young voters make up 19 or 20% of the electorate and vote for Obama by a 23 point margin, this is going to be a blowout up and down the ballot.
