Is it flip or flop?

What do you make of a public official that derides a bill as being bad for his district yet at the 11th hour with pressures and assurances from the White House changes his vote, even when the bill is not changed? Unprincipled you say???? You see, there are times when being an American trumps being an elected representative of the 8th district of NC. Don't congressman take an allegiance to support and defend the constitution of the United Stated of America? WE NEED PRINCIPLED LEADERS!!!!
