this is the sort of tough, serious ad...
... that wins uncommitted voters. yes we libertarians often believe in open borders, and that would be my preference personally. but at a time when we've kicked so many hornet nests and have so many threats (yes, i see the threats as real, i just don't buy into the reasonings or solutions offered by the other candidates), an open border is a very bad idea.
now, let's take the 'terrorist nations' item. 15 of the 19 hijackers were saudi. that doesn't make every saudi a terrorist, it makes saudi suspect in general, and i don't have a problem with saying "Country X has been exporting a lot of terrorism, either via government or otherwise, so let's stop letting them in without very good reason, for a while, til they clean up a bit."
this ad will grab attention in IA
