I think most of the comments here support this general self-assessment. (God knows that anyone in Gen X was all-too aware of the fact.)
P.S. Obama, born in 1961, is on the X/Baby Boomer cusp. But given his single-parent upbringing and general awesomeness, I have always considered him our first Gen X big-time leader. The biggest unspoken issue of the 2008 campaign is our movement away from a Baby Boomer or GI Generation president in a very very long time (Eisenhower was our last Pres not from GI/Boomer Generations). McCain, born in 1936, would be the FIRST member of the Silent Generation to become President, ever (Bush II: Boomer; Clinton: Boomer, Bush I: GI; Reagan: GI; Carter: GI; Ford: GI; Nixon: GI; LBJ: GI; JFK: GI; etc.). The real question of this election is: do you want someone from the old school that can't logon to a computer leading us in the 21st Century, or would you give that task to one of the do-nothing, lazy, slackers that you have come to know and love?
