Why Trump is important

Vox Day nails it:

That leaves immigration. And here, Trump is the only candidate who is even beginning to address the scope of the existential problem. All the Democrats, and more than half of the Republicans, actually want to make it worse. Even if you don't support him, or trust him, the mere fact that he is in the race has changed the debate on the subject more than the combined efforts of every anti-immigrationist, every open-borders skeptic, and every anti-free trade economist. He has been a literal Godsend in this regard, no matter what happens in the end. 

In short, Donald Trump has radically changed the culture, and culture always trumps politics. And that is why petty sniping about the usual politics is not only pointless, it demonstrates that you are too stuck in an intellectual rut to even understand what the rest of us are discussing.

You don't have to support Trump to see that he has pushed the topic of conversation away from what the Democrats want, and towards what the conservative voters want.
