That's how we used to successfully do it!
Candidates need to get rid of "campaign consultants".
In one conversation I had with a consultant I stated that door to door and targeted mailings were the way to win elections and that TV was not only expensive but a waste of money.
He actually agreed with me and then stated that if he ran a campaign on my basis it would take him full time to do it but if he ran a TV and media campaign he only had to work about 2 hours a week and make more money per campaign.
We used to put together enough people to hit every precinct in a district in the last 2 weeks before the election and if a district was 39% Republican we considered it a winner, and it worked.
In recent years the democraps have understood what we were doing and have copied it and been successfull.
Since the big money country club Republican RINOS have taken control of the state party it's gone all to consultants and cut out the conservative Republican clubs that provided the on the ground people and we now can't win an election unless there is a majority of registered Republicans in the district.
TRUTH ALERT!!!
