A new pol shows Senator John McCain (R-AZ) is vulnerable to a primary challenge from the right. In response, he's busy flip-flopping his way over to oppose bipartisan climate-change efforts.
I have to say, I'd be thrilled if John McCain loses a primary. From my perspective, it's win-win. His reputation for bipartisan maverickism has always been overstated, so it is not like Democrats are losing a member that is easy to work with. But a primary defeat would set off a torrent of "the GOP has been hijacked by a far-right base and has no room for moderates" reporting by a punditocracy that still, beyond all reason, sees McCain as a national bellweather.
Plus, it gives Dems a fighting chance to flip the Arizona seat.
It's all good from my vantage point.
