You are right, I stand corrected; but worse than that, Cao, was the only one of the 177 House Republicans to support the health-care bill.
But do you know the circumstances? Cao was the very last Representative to vote. Boehner held him until the last because a.) if his vote was needed to defeat the measure, he was going to vote "No" or b.) if his vote was irrelevant to the measure's success, Cao would be allowed to vote "Yes" -- reflecting the wishes of his dirt-poor, mostly black district.
As it happened, the measure passed by two votes. Cao's vote made no difference -- so he was allowed to vote "Aye".
But the important thing to remember is that, if his vote had been needed, he would've been there.
You will never, and I mean never get a more conservative representative in that district. Cao is doing well considering. His 55 acu rating is far superior to the 2 acu rating you’d get outta anyone else from there.
