The consensus seems to be that the Republican race really is wide open. Powerline:

So who is the Republican front-runner now? There is none.

Mark Levin:

If Romney retools his campaign and presents himself as a moderate businessman able to bring better management to Washington, he finally has a message that could work. Of course, it's just the latest poll-tested cynical ploy. But it's working for Clinton! And she and Romney have one thing in common: two focus-grouped cynical dynastic holograms.

I need a drink.
