We may be toast already, and because of LEGAL immigration, not because of Amnesty.
The USA creates about 1 million new citizens per year.
New citizens vote 80% Democrat, but their turn out is very low.
The only reason Conservatives still have some political power is because our voter turn out is the highest in the country.
When Socialist voters start to vote at the same rate as Conservatives, the game is over.
For the record, voters turned out for the socialist party in far greater numbers both in 2008 and 2012, but I'm not sure they understood they were voting for the things the socialist party has been implementing or wants.
As to the issue on this thread, Johnny's amnesty fixation, IF we're not toast already, the amnesty bill concocted by the senate (or any facsimile of it) would burn us to a crisp.
