I think that this issue is a good one to let the GOP candidates run on their position in November rather than allowing the Dems to use every opportunity to stonewall so that the GOP gets the blame for inaction.
There is time after the election to deal with immigration.
There already is an amendment to the Defense Appropriation Bill for fencing along the Mexico border...
So..regardless of whether the actual Immigration Bill is decided or not...there WILL be a fence built, and more guards hired...and additional units to keep the illegals so there won't be any catch/release anymore.
There is already money and programs allocated for quite a bit to be done down there...and so after the election will be soon enough.
What's to deal with? Enforce the damn laws.
