McCain and Sen. Robert Menendez (D-N.J.), another senator in the working group, each expressed cautious optimism on "This Week" that the reforms they will be proposing can be passed.
McCain said the outcome of the 2012 election should convince Republicans that a pathway to citizenship should be passed.
“Let me give you a little straight talk,” McCain said. “Look at the last election. Look at the last election. We are losing dramatically the Hispanic vote, which we think should be ours, for a variety of reasons, and we've got to understand that.”
