If you have seen how vast OFA is and how embedded they are at the precinct level even in deep red states... yeah, I would be worried. The right just does not have a similar targeted GOTV organization.
GOTV is worth 5-8 points on election night. Maybe more.
The only thing similar on the right is
American Majority. They have a ton of good resources and are setting up training all over the country. But it is late in the game and the left is light years ahead.
