Wise words from a leader I respect immensely. I think if he ever ran for POTUS, he could practically walk right in he has such integrity and respect from so many Americans. A shame the GOP has moved soooo far to the right of the moderate, pragmatic Republicanism he represents and I think his critique is spot on that the GOP needs to do far more than simply polish up its facade and presentation to become again a viable major party into the future.
I say all this, not as some raving left wing liberal, but rather, as a more pragmatic moderate who actually once worked for a Republican Senator many, many moons ago. It is an interesting question though, given the GOPs rightwards devolution of the past 20-30 years, as to why he's still a Republican for it seems the party he remembers has essentially already left him where he's been standing all along.
