With the bill in effect
All of the 270+ presidential electors from the enacting states will be supporters of the presidential candidate receiving the most popular votes among all 50 states (and DC)—thereby guaranteeing that candidate with an Electoral College majority.

It would NOT be direct elections.

The founders created the Electoral College, but 48 states eventually enacted state winner-take-all laws.

Unable to agree on any particular method for selecting presidential electors, the Founding Fathers left the choice of method exclusively to the states in Article II, Section 1
“Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors….”  
The U.S. Supreme Court has repeatedly characterized the authority of the state legislatures over the manner of awarding their electoral votes as "plenary" and "exclusive."
