Triggers and bipartisan commissions won't prevent the erosion of our sovereignty

Marco Rubio has seemed like such a principled guy, but I'm leaning toward the camp that finds his basic judgement questionable.  I've heard him defend his immigration views on several talk shows, but it still seems to me to boil down to an arcane version of border-enforcement-plus-a-lot-of-nothing.

John T. Bennett at The American Thinker is convinced of it.   He points out a good reason to believe that the probable scenario of unfolding would remove any bulwark against wholesale amnesty:

If the border effectiveness triggers are not reached in five years, a bipartisan "Southern Border Security Commission" will be established (Sec. 4, p. 14).  This Commission is supposed to "submit to the President, the Secretary, and Congress a report setting forth specific recommendations for policies for achieving and maintaining the border security goals" ([d], 17).

Picture the political scene in the near future after amnesty has passed.  The country, and especially the estimated 11 million illegal immigrants here, are eagerly awaiting the upgrade to lawful status.  The GOP's amnesty supporters are convinced that they've locked down the Latino vote, which "should be ours," claimed John McCain.Because no promise to secure the border, properly enforce E-verify, or even deport known criminal illegal immigrants has ever been met, we can be assured that the bipartisan Commission will take over.  Marco Rubio has basically conceded this point.  In his current talk radio campaign, he repeatedly emphasizes the Commission whenever he's reminded that the federal government habitually lies about immigration enforcement.So picture the bipartisan commission, meeting to discuss the future of 11 million people who expect amnesty, and are now getting more upset that politicians are dithering with their perceived entitlement.  (Can there be any doubt that illegal immigrants will develop an entitlement attitude towards citizenship if amnesty is passed?)So we're a few years down the road, the entitled illegal immigrants are angry, and a good number of citizens are still angry that amnesty passed to begin with. The pro-amnesty Republicans are starting to worry a bit as well.  All this pesky border talk could interfere with their rightful hold over the Latino vote.Not to worry -- the bipartisan Commission steps in.  But what do bipartisan commissions do?  The bipartisan budget super-committee failed to reach a deficit reduction deal in 2011.  The bipartisan Simpson-Bowles proposal was rejected by...a bipartisan vote in 2012.

What, I would like to ask the Senator,  is wrong with the basic approach of just enforcing the border now and taking whatever time is necessary to decide how to deal with the illegal aliens already here?  What's the rush?
