My own reaction to those who raised the non-issue, disprovable by the passport issuance, was Fuck 'em, it's bad faith racially bigoted bullshit.
What was your reaction when it was raised against McCain? It probably insulted his intelligence also. But he did not let it linger and use it for years to divide people. He immediately cleared it up for the doubters.
Why didn't it dog him in his state legislative career, his stint in a law firm, his job as a Constitutional Law instructor at the U. Of Chg. and in his successful run for the U.S Senate?
Is that a requirement for any of those stints?
