I’ve seen lots of Dewhurst ads on TV, but have not seen even one Cruz ad.
Don’t know the finances of Cruz but as you know Texas has some very expensive media markets so it may not be possible for him to do TV in those areas: Austin, DFW, Houston, etc.
I’m in Houston & have seen plenty of Cruz ads on tv, many of them lately rebutting the Dewhurst ads criticizing Cruz. To look at our mayor & the infamous congressWOMAN you wouldn’t think Houston is any less prog than Austin, but when you count all the suburbs perhaps we are seen as a better use of limited funds than Austin ad buys.
