Trying to SKYPE with F-Pod...

Roger hoped I would Skype from the Franklin D Roosevelt Memorial, but apparently students on F Were not able to do so today....bummer! I was ready to go.... Franklin D Roosevelt was elected to a whopping FOUR terms as president.....and he had a disability! He was diagnosed with polio at in 1921 and never walked unassisted again! Much of his presidency was spent in a wheelchair!
1. Why did many Americans NOT know he was in a wheelchair??
2. If Roosevelt was elected to four terms, why did he only serve 12 years?
