Nonsense at the top of a ladder

University of Wisconsin Professor Kenneth Mayer comments on the Barron’s story that I noted yesterday morning:

That Barron’s story is, as they say here [in Australia], nonsense at the top of a very tall ladder. Among the problems:

(1) warchest size is not an independent variable – rather, the size of (in particular) a challenger warchest is a proxy for how competitive a race is expected to be;
(2) you’d be an idiot to ignore the vast amounts of polling that give a much better indication of how a race will go;
(3) the incumbent reelection rate isn’t necessarily better, since incumbents don’t always run for reelection (open seats, of which there are usually 30-40, are much harder to call);
(4) incumbents almost always outspend challengers;
(5) the data they are using is from the September 30 FEC filings, so it can’t take into account the last 5 weeks of the campaign.

This story is a variant of the odd phenomenon, that the more incumbents spend, the worse they do, since incumbents tend to spend a lot when they are in trouble.
Like a John Edwards prediction, they’ll get credit for being contrarian geniuses in the (hugely unlikely) even that they’re right. If they’re wrong, everyone will forget about it.
