Referring back to your astute "blurred lines" observation, the GOP has lost its way through the Moderates "Big Tent" ideology enabling more Progressive infiltration, which also includes the Party's Conservative base and their troubling Alinsky aversion cowardice, so, what appears a Republican now merely goes along with the openly Marxist vocal Democratic Party that greatly enjoys feeding the ever expanding waistline of a cradle to grave mother government.

For record, that quoted FMCSR law obviously has no teeth.  I give you, Caliph Hopeandnchange and the latest smokescreen for the H. W./BJ Clinton NAU scheme.

The North American Free Trade Agreement, or NAFTA, included a provision that the United States and Mexico would allow each other's trucks to haul cargo across the border for delivery anywhere inside the other country.

To comply with NAFTA, the Obama administration in April proposed a three-year pilot program with requirements for Mexican truckers that include a preliminary safety audit, purchase of U.S. insurance, English proficiency for drivers, truck inspections for every border crossing for at least the first three months, an 18-month probation period and a three-month renewal period for safety inspections after permanent authority is granted.

And still with no Official language of the United States of America?  Ya, like that '3 year "pilot program" requirement' 17-fricken-years after NAFTA was law would somehow fly in the radical Ninth Circuit.  Riiiiiight.  They got their way before, they'll get it again.  This usurpation of our sovereignty scheme is both gobsmacked laughable and hair-raising disturbing all at the same time.

More disturbing is the roach motel of the Kakistocracy still actively has most of the kleptocritters from 1993 that enabled the usurpation in the House and Senate.

Hell, the one from Ohio that voted Aye was recently out tanning on the fairways with Caliph Shankopotamus is now Speaker!
