On the Democrat side of the political ledger, it appears the voter base is divided by age as much as anything else. Younger voters, especially those aged 18 to 29, are trending heavily toward Sen. Barack Obama, according to exit polls conducted after primary and caucus contests on Super Tuesday, Feb. 5. Nationwide, Obama held a 19-percentage-point lead among those voters.
Older voters, however, those 45 and older and especially those aged 60-plus, favor Sen. Hillary Clinton.
