We live in an era of stark political division, but there's at least one aspect of politics both sides agree on: a maximum age limit for elected officials. Most feel that after a certain age they should not be permitted to hold office.
There isn't just agreement across political lines, but across demographic groups, like age, too. Young and old, including seniors, favor maximum age limits for elected officials.
And far more Americans believe additional young people in elected office would be a positive for U.S. politics than a negative. So what should that age be? When offered a list of ages, Age 70 is the top answer chosen. This is older than the current average age of members of Congress, but about a third of current U.S. senators are 70 years of age or older.
