I think he’s advertised on 1070AM and/or 700AM but he needs to reach out to OTHER voters in the district.
Biggest thing he needs to do is to replay Queen Shiela’s quote were she says she has the “dishonor” of representing Texas in this district.
OH yeah, if he would just hammer away at this line he'd do excellent. You know, postcards are pretty damn cheap. Heck I know of a website where you upload the template, upload the spreadsheet, it does the printing and the mailing!
He could literally put something in the hands every week, and one neighborhood this week and one next week, and just highlight the dishonor thing.
