Of course we’ll never know if a Gore presidency would have spared us Obama. It would be nice if we could know what was going to happen as a result of different people being in power.
Many here wish that Bush had never been elected, but that ignores that his Democrat opponents would have been president instead.
It’s pretty safe to say 9/11 would have happened under Gore as well. However, there would have been more pushback here against everything that came after it, instead of excuse making because an (R) was POTUS.
