The Washington Post has done a study of the age range of all 20 Democratic Presidential candidates.
It turns out that half are under age 50, and half are ages 50-77.
Four are age 40 and lower, and six are between 40 and 50.
Four are in their 50s, and four are in their 60s, while Bernie Sanders and Joe Biden are in their mid 70s.
Of course, all 20 Democrats will be nearly two years older when the inauguration comes.
Interestingly, both Bernie Sanders and Joe Biden are in the lead in polls, despite their age, while two women, Kamala Harris and Elizabeth Warren between 50 and 70 are right behind them, and with Beto O’Rourke in his 40s also competing, and one of the four below age 40, Pete Buttigieg, also doing well at this point.
So we have a wide variety of age distribution, and the question is how the different age groups will vote once the primaries and caucuses begin in about 10 months.
