If he doesn’t get 270, then the election goes to the House under the terms of the 12th Amendment.

No. The winning candidate has to have a majority of the electoral votes certified in the election. Assuming all 538 EVs are certified, this means the winner has to get 270 or else it goes to the House ... and the House can select any of the top three candidates who got at least 1 electoral vote.
