No pat answer. Depends how many points of each type you have stored up.
Some Founders will re-appear if you pass them up (provided no one else snags them). Others won't. I think if you have more points available than a Founder costs, he won't reappear.
A lot of Founders have gimp abilties. Just skip them, grab the useful ones, and then if towards the end you can get some that you passed up, yay. The important thing is to get the Founders that really benefit you (such as Pocahontas, Ben Franklin, James madison, etc)
the xml quote by the ones who check say the contrary
I know many of the same founders were offered to me over and over again, during the 8-9 turns I waited to build points. If I wasn't refusing them, what was I doing? I was surely passing them up...

I've had quite a few founding fathers pop up a second time.
This is weird.Some forumers seem to get founding father to pop up again, some don't. Personally, I have never seen that happen. I've played quite a few games now, and it never occurs.
