You are describing a character flaw. Cruz's biggest problem is his claim to fame is following the original intent of the Constitution.. Yet, he daily demands an exemption for himself. Liberal lawyers are not going to ignore that hypocrisy. I expect more than a few liberal lawyers and judges to find religion and decide to play 'original intent' upon Cruz.
Just because you and I see it as a character flaw, doesn't make the public see him that way, and public perception is reality.
I'm not sure the liberals will rain on his parade. There is a bigger goal at stake here, and that is erosion of nationalist sentiment. We are on our way to becoming a place on the earth that harbors all and varied ethnic and cultural enclaves, pooling resources for the common good. This "NWO creep" is going on all over the planet.
