Voters should decide how much a candidate's age matters.
Lately considerable attention has been focused on Sen. John McCain's age, with some saying he is too old to be president.
If elected, McCain would be 72 at his inauguration, making him the oldest man to become president. If elected to a second term, he would be 80 at the end of it - also the oldest ever. Ronald Reagan, who was almost 78 when he finished his second term, is the oldest to serve as president so far.
