Yet in reality, the reverse was actually what occurred during the last 2 elections-
A Closer Look at
Older Americans
The vast majority of Americans who are 65 and older are members of the Silent generation (ages 66 to 83). They came of age in the Truman, Eisenhower and Kennedy years. Silents favored the Democrats at times during the 1990s, but in recent elections have strongly supported the Republicans. While they aligned more with the Democrats in the 1990s, they have become much more Republican in recent years. The Silent generation replaced the Greatest generation, who were more reliable Democratic voters when they constituted the bulk of the senior vote.


Silents increasingly call themselves conservative and they hold the most consistently conservative views about government, social issues and Americas place in the world. Unlike other generations that in recent years have become more supportive of smaller government, they have held conservative views about government for years.
Today, an overwhelming majority of Silents are either angry or frustrated with government. They are the generation that is most strongly disapproving of Barack Obama, for whom a majority did not vote. Silents also are the most politically energized generation, as they demonstrated in the 2010 midterms.

The fact that a "coalition" of America voted for this current President is still heartening as this shows that the tide is changing but we still have a ways to go.
