David Pearce (r) is term limited. Denny Hoskins (r) is term limited out of the House. Mike McGhee (r) spent a whole lot of other people’s money challenging David Pearce (r) in the primary four years ago. Maybe it’ll be a similar story this time – the money part we mean.

We can’t wait to see the ads and mailers.
