If there was a war against our nation that he was fighting, why were our borders left wide open?
He most certainly DID NOT "leave the borders open". He tripled the border security budget and the number of border guards both federal and civilian. He signed the bill for the fence in '06 (Obama cancelled it), he HUGELY inflated the number of on-site business raids by ICE, deported and jailed massive numbers of illegals.
The Democrats and Obama have been working for 18 months to overturn everything he did to protect the borders, but none of the facts matter because people like you prefer to believe the Bush-hating flying monkeys. It really is boring.
