This article seems to add a dimension to the whole thing. The administration does not support the views of a large part of its constituency on this issue. Having a Senate Majority leader supporting border security would have been huge.
That said, I think that we can expect some further fall out, now that the Left has successfully flexed their muscle. Although that success reflected more the lack of moral fibre among politicians in general, rather than anything persuasive in their argument, it has encouraged them. And, as a practical matter, the need to get our borders closed to third world immigration, will encounter a lot of nasty rhetoric by those who will suggest that it is "racist" to want to maintain the traditional character of the population. They will continue to play that card until we stand up and demonstrate that it will not work for them.
Our position is not hopeless. But we need to rediscover the basic values, which have always included family ties, common culture, kith and kin and shared history--that a nation is not a game of musical chairs.
