Also from the DNC, which produced this video:
"After watching him debate himself on immigration reform at NALEO today, it's easy to see why John McCain wanted to make last week's meeting with Hispanic leaders in Chicago a closed-door event," said DNC Communications Director Karen Finney. "Apparently, Senator McCain's idea of 'straight talk' means giving two different answers to a straightforward question about whether he supports comprehensive immigration reform or an enforcement-first approach to the issue. McCain's promise to vote against his own comprehensive immigration reform bill is yet another example of his election year conversions on the critical issues facing our country."
Maybe he's just confused, like with the economy or that whole Sunni/Shi'a thang? :)
