Popover - show different ad based on visitor's country

I've got a case where I need to show a different popover to users based on their country.

-- If user is in the US >> Show the US popover
-- If user is in the UK >> Show the UK popover, etc...

I've got a Geolocation plugin that returns a javascript variable on page load with the visitor's country code, like this:

mmjsCountryCode = "US"

I'd like to use a simple if/then statement based on this variable to show the right popover to each user for the countries I've set up.

Is this possible using the current rules?
