There's a new measure for politicians -- their intensity score. Or at least it's new to me. Gallup reportedthat Herman Cain's intensity score had taken a dip, so we thought it might be interesting to see how Scott Walker is doing.

The intensity score measures the people who say that they have a strongly favorable opinion of a candidate against those who have a strongly unfavorable opinion. You subtract the negatives from the positives and see what's left.

These are not entirely accurate because they ask about Walker's job performance rather than his personal popularity, but it's all we've got. Three recent polls:

The Republican firm, Rasmusssen Reports, Oct. 26: 38-38 on job approval, for a net of zero on the intensity index for Walker.

Wis. Public Radio/St. Norbert poll this month: 19 very favorable, 39 very unfavorable on job performance. Net -20 for Walker.

Finally, Walker's friends at the right-wing Wisconsin Policy Research Institute: 24 very favorable, 45 very unfavorable on job performance. Net -21 for Walker.

Couple that with recent polls showing most people favor recalling him, and things get interesting. If the vote were up or down on Walker, he'd be gone. But that's not the choice.

We need a Democratic alternative who can beat him. That position is still open.
