Why do you say "Liberal" plan?  That would make sense if their plan was different than the others, but every single party has the exact same immigration plan.

Notice how NONE of the opposition parties - not even the CPC - took any issue with the latest immigration plans?  They all supported them.

So where do you get this "liberal" plan from?  Its actually easy to argue its a conservative plan.  Heck Germany is run by conservatives and they're the poster boy for migrants.
