	USAGE!
	Stick this in your page somewhere, with the div you want to inject the new content into as the argument. 
	Here, the injected_div is `.index_polls`. For it to work, you need to have a raw version of your content to inject.
	The raw version should take the format <page>?format=list_only&page=[pagenumber].
