Voters Head To Super Tuesday Polls [VIDEO]

Voters from Vermont to Colorado, Alaska to American Samoa and a host of states in between were heading to polling places and caucus sites on the busiest day of the 2016 primaries.

The contests come at a turbulent moment for Republicans as they grapple with the prospect of Trump becoming the party’s nominee. Rivals Marco Rubio and Ted Cruz are engaged in a frantic effort to stop the billionaire – with Rubio in particular lobbing surprisingly personal attacks – but it was unclear whether they’d made their move too late.

“This is a movement,” Trump told supporters at a rally Monday evening in Georgia. “I’m just a messenger, folks.”

Like Trump, Clinton has won three of the four early voting contests, including a thrashing of rival Bernie Sanders in South Carolina on Saturday. Her victory there was due to overwhelming support from black voters, putting her in position for a strong showing in several Southern states with large African-American electorates that vote Tuesday.
