OK, let me give this a real try:
1 someone else alread has - Blaine from Maine
2 no clue - I will be mad when I hear the answer, wishing I had thought of it
3 Again, had to be someone inaugurated on March 5 since March 4 was a Sunday that year.
4 no clue
5 Someone got this - Gerald Ford, oldest President ever (?)
6 Dunno - all presidential nominees, but I bet the answer hads nothing to do with that
7 Coolidge - born on July 4 (?) - I didn't google it, but I think that's right
8 Dunno
9 Washington - Inaugurated on April 30, not March 4
10 Born on Feb 22 - thank GOD no other similarities!!!
:)
10 must be wrong - maybe "born in February" is the answer
I'm trying not to "cheat" with google.
That's not the question though. Half the answer is "Have the same birthday." The other part is to find the two presidents that actually do share a birthday. (Which should be trivial enough to Google.)
