Can't tell what they are measuring from the chart alone.
eg.
IV: "mudslinging", ULC -0.07(0.03) ... would appear to be saying that mudslinging in the campaign has a slight negative effect on voter turnout but what are we to make of:
IV: "tone of the commercials" ULC 0.12(0.06) ... ?? I mean, what does "tone" measure and how was that measure turned into a logit coefficient?
You should look to see what they are "coefficients" to.
Whatver they are: the beta would be the same as the ULC only with their statistics standardized to unit varience. eg. they are showing the same thing in the sense that bigger numbers mean favorable ratios for the IV. The standardized measures are usually more useful for comparing different IVs to each other.
