Yes, Nader cost Al Gore the presidency in 2000.

234. Florida would have been enough by itself.

Yes, the complete recount taken after the Supreme Court suspended the count did show that Gore won if every vote in Florida would have been re-counted.

In any case, it would have only taken a fraction of Nader's votes in Florida in 2000 to have allowed Gore to have won the presidency without challenge. With those electoral votes, we would have had the most pro-environmental President in US history and we never would have invaded Iraq, and hundreds of thousands of people would not have been killed or maimed.

There also is a very high chance that President Gore wouldn't have gone back to clearing brush when he was handed intelligence saying "Bin Laden determined to attack inside the US."

The sad thing is - this situation was clearly evident in the weeks before the election. People begged Nader to suspend his campaign in Florida, but instead he redoubled his efforts. Then a system was set up to allow vote trades over the internet. People who wanted to vote for Gore in solid blue or red states would agree to vote for Nader. In return, the Nader supporters would vote for Gore in the swing states. This system was widely publicized and was intended to allow the Nader supporters to still be heard without causing a Gore loss. Nader publicly condemned the effort.
