Doubts about Thompson

George Will articulates the doubts about Fred Thompson that many conservatives are -- or should -- be feeling. It's been remarkable to watch him be compared to President Ronald Reagan when, as Will points out, Reagan's ideas were his calling card whereas Thompson's proponents seem most enamored of his manner.

It's also fair to ask -- is Thompson's late entrance into the race just good political smarts, or does it signal an unwillingness to put in the time, and maybe even a paucity of ideas and preparation?

Tough questions, indeed, but better to know now than after someone wins the nomination.
