CLEARWATER — Perhaps the best evidence of Tom Emmer’s commanding position in his campaign for Congress is this: He’s not allowed to wear his rollerblades.

The image of Emmer skating down parade lines, shaking and slapping hands, has been a staple of hockey-dad persona, but his handlers said no this year. As the GOP’s defeated 2010 governor candidate tries to restart his career with a win in Tuesday’s primary, a broken bone, it seems, is all that could hurt Emmer’s chances.
