It wouldn't be done by Trump's political allies to make sure he won (remember voting is fake and gay), it'd be done to make him into a mythical figure. The messianic rhetoric around Trump is higher than it's ever been at this point and will only continue to build. This perception will make many people follow whatever Trump institutes or says. For example, something that could be easy to see given Trump's persistent displays of love for Israel would be drumming up support for war with Palestine. Because Trump is now seen to have the Mandate of God, people will not only unquestionably follow but they will do so enthusiastically.

It also has the bonus of ratcheting up tensions along political lines which is almost always a good thing for tptb.
