I know that most of you feel that Beto going into the rural counties is reaping minimal results when it comes to votes and everything should be focused on the big metro areas.
However the Wendy Davis campaign (in conjunction with Battleground Texas) decided to completely ignore the rural vote in 16, as well as most of the white vote. She lost by double digits with that strategy. So while he might not win by turning out an additional 3% podunk vote, he'll certainly lose by not paying attention to what he already has there. And the other down ballot people are out there pressing flesh and making speeches, touring as well.
Every one of these stops is getting local TV and print coverage, for free. The MAGAs showing up just make it even more appealing to the news people. He is getting tons of exposure on all the social medias as well. IG, twitter, TikTok are full of folks reposting his content, as well as Collier's, Warford's, etc. We can't fight the huge war chests for TV ads, but social media is a boon to cash poor but follower rich candidates.
Plus the timing of this tour is good, because it's a period right before Labor Day when all the races really dig in and run hard. So he's out there working the smaller counties and saving his time in Sept/Oct for those larger metro areas.
