Although the story doesn't mention it, this plan would actually make it harder for Republicans to win, because they need all of Virginia's electoral votes:
ProgressVirginia reported Tuesday afternoon that the Virginia Senate’s Privileges and Elections Committee killed Sen. Charles “Bill” Carrico Sr.’s electoral college-rigging bill, despite an offer by Carrico to amend the bill to award electors in proportion to the state’s popular vote. The vote was 11-4 against the bill, although it will not be official until the close of the committee meeting.
