Google +1 and changing site name without www
 

Hi,
I changed the website URL from http://www to URL without "www", using also 301 redirect in htaccess.
Now, all the +1 Google which was for the name with www disaperred.
It is not such a big deal, but anyway; is there a solution to get the +1s votes from the old address with www to the address without "www"?
