That is why Democrats in Washington D.C. don't take Republicans seriously when they say they want to talk about immigration.
Democrats know a steady stream of people will continue to pour into this country without repercussions. Why would they negotiate? They are winning.
That is why it is time to get tougher on immigration. Start arresting people. And keep arresting them until Democrats decide they're willing to negotiate.
There were 'thousands' of immigrants in Madison yesterday. That'd be a good place to start.
Yes, people will be angry. Yes, the headlines will be grim. But unless something changes, nothing will change.
