Also i believe George Bush and Bill Clinton are related by blood as well and are cousins of some sort. So if you want to talk about the "Bush family" dynasty, it's really kinda been non-stop since George Bush Senior.
If you think that's bad you should see how many presidents FDR is related to.
Obama also apparently is related to a figure in the current whitehouse....
Dick Cheney... and I guess also Bush. So oddly the only way to get out of the "Bush Dynasty" is to elect John Mccain. I know I didn't see that one coming!
