The Hispanic population will continue to grow faster than others.
Amnesty will not stop illegal immigration...
But some form of amnesties and illegal immigration with both continue into the foreseeable future.
Also, illegal immigrants will not be deported won't happen.
Few will leave of of their own accord. Living in squalor here probably beats living in squalor in their home countries.
And a two language nation (like Canada) may very well evolve here.
Meanwhile, the growing illegal population grows the underground economy...
And the underground economy is a drain on the national economy.
A massive subculture is the last thing we need.
Presently, most illegals live in poverty...
And people living in poverty tend to be a big Democrat constituancy.
Illegals, by definition, are fugitives...
And more fugitives will cause more problems as they prey on us to survive. It's already happening and increasing.
Therefore, they will be legalized (via amnesty) and they will become voters.
They will also become tax payers.
How many potential voters are we talking about?
No party can afford to concede that many votes. That's the political reality.
If we don't assimilate them under our terms, they will assimilate themselves under their own terms.
Without assimilation, all the problems you can think of will become more and more unmanageable and much more expensive to solve.
This all represents the price we will pay for generations of open borders.
No one party alone will fix the problem, but the two major parties working together can make a big difference. Don't count on the Democrats to help. They want the current and potential millions of votes.
Addition:
Don't count on Republicans to help. They're busy Hispandering for votes and are in bed with the businesses that hire illegal aliens.
