How can you tell your field kind of sucks?

When it has tremendous volatility.

Three weeks before the Iowa caucuses, Republican voters across the country appear uninspired by their field of presidential candidates, with a vast majority saying they have not made a final decision about whom to support...

Not one of the Republican candidates is viewed favorably by even half the Republican electorate, the poll found. And in a sign of the fluidity of the race, former Gov. Mike Huckabee of Arkansas, who barely registered in early polls several months ago, is now locked in a tight contest nationally with Rudolph W. Giuliani and Mitt Romney.

When not one of your candidates has a winning favorable score, EVEN WITH THEIR OWN PARTY, you have problems.

Meanwhile, Grandpa Fred has lost everyone but David Broder.

Mr. Giuliani was the choice of 22 percent of respondents, Mr. Huckabee of 21 percent, and Mr. Romney of 16 percent. Mr. McCain and Fred D. Thompson each had 7 percent.

Thompson was, if I recall accurately, the second choice just a few months ago. Until he ran for President with less vigor than he didn't run for President.

Honestly, Fred's exercise program appears to be wearing flannel pajamas.
