What features of the Constitution make it flexible enough to apply to the nation's needs today?
It's purposely vague in some parts. But the main way that the Constitution is able to keep up with the times is the Amendment process.
I especially remember the 26th Amendment, passed in 1971. The U.S. was fighting in Vietnam and drafting young men who were as young as 18. Yet the lowest age that people could vote was 21. Wait a minute! That wasn't fair to draft kids who couldn't even vote. So this amendment lowered the legal voting age to 18.
