Same Poll Multiple Sites

Sorry if this has been discussed. I have looked through the forum and did not find exactly what I am looking for.

I have 3 different sites. I would like to add the same poll on all three of them.

I do not want each site to have it' own, but some how have it set up on one, but on the others having the script somehow point to and display from the main one.

I hope I have made it somewhat clear as to what I mean. Any direction would be greatly appreciated.
