As electoral college voters met Monday, many went rogue — but not from President-elect Donald Trump as was expected.

Several "faithless electors" who cast their presidential ballots Monday for someone other than Trump or Democratic presidential nominee Hillary Clinton did so in support of Clinton's Democratic primary challenger, Vermont Sen. Bernie Sanders.

As the Minneapolis Star Tribune reported, Muhammad Abdurrahman, one of the state's 10 electors selected to cast a vote for Clinton, voted instead for Sanders. He was then replaced by an alternate who voted for Clinton.

Maine elector David Bright also declared that he would vote for Sanders in lieu of Clinton. In a statement, Bright said that he was not a Clinton elector, but a Democratic elector.

Bright said:

I cast my vote for Bernie Sanders not out of spite, or malice, or anger, or as an act of civil disobedience. I mean no disrespect to our nominee. I cast my vote to represent thousands of Democratic Maine voters ― many less than a third my age ― who came into Maine politics for the first time this year because of Bernie Sanders.

But despite his proclamation, Bright's vote for Sanders was ruled to be improper, and he voted for Clinton after all, according to The Associated Press.

As the AP's Nick Riccardi reported, a similar situation happened in Colorado as one elector was replaced after he declined to vote for the former secretary of state.

Washington state also saw four so-called "faithless electors" go rogue as only eight of the state's 12 electors voted for Clinton. Three electors reportedly voted for former Secretary of State Colin Powell and one for Faith Spotted Eagle, a Native American activist, according to the Seattle Times.

Despite nationwide protests and last-ditch efforts to attempt to sway Republican electors from voting for Trump, GOP electors appear to be voting overwhelmingly in accordance to their states' rules.

And Trump seems to be on track to securing the 270 electoral votes needed to solidify his presidency.
