Correcting False Impressions

According to Jacob T. Levy

Rachel DiCarlo, at the Weekly Standard's website, repeats the claim that Libertarian Kurt Evans cost Republican John Thune the South Dakota Senate race. As I've blogged before, this claim is almost certainly not true. While Evans did indeed get more votes than separated Thune from Johnson, that was weeks after Evans had dropped out of the race and endorsed Thune. This means that the Libertarian-Republican swing voters are very likely to have swung to Thune. (The 3,000 votes represents a much smaller share of the vote than Evans was picking up in polls before he dropped out.) The remaining 3,000 probably wouldn't have voted for Thune in any event; and on net Evans helped Thune (first, by swinging his way those voters who could be swung; second, by keeping 3,000 of the other voters from voting for Johnson).

Interesting, I wonder if Ralph Nader is likewise keeping Green voters from voting Republican.
