And now there's more.
An outside group, AmericansForAmerica (creative!), has hit the radio waves with an ad tying Paul's critical stance toward mine safety with the recent horrifying but ultimately happy story in Chile.
Like Paul's own spot, it's a rough ad. But Paul really has consistently taken an 'accidents happen' approach toward mine safety and other industrial disasters. So it would be expecting a lot for an opponent in a tight race not to pivot off a major mine safety disaster (albeit one with a happy ending) to highlight those views in a mining state.
Late Update: Conway and Paul met up last night for a nasty, angry debate which turned largely on Conway's new ad. See our report here.
