Following heated Democratic and Republican debates Sunday and last Thursday, respectively, the remaining presidential candidates turned to a slew of upcoming first-round voting events across the nation slated for Tuesday and March 15. With national security, economic prosperity and social services among the top campaign issues, candidates are expected to move their campaigns to the Midwest and Southern United States in the coming weeks.

"Always vote for principle, though you may vote alone, and you may cherish the sweetest reflection that your vote is never lost," former President John Quincy Adams once said.

Residents of states participating in the primaries and caucuses on these dates can find their closest polling station by clicking on the link for the name of their state and then following the instructions to enter district numbers and any other relevant information. Hawaii will host a Republican caucus and Idaho a Republican primary Tuesday. Michigan and Mississippi will hold Republican and Democratic primaries the same day.

Florida, Illinois, Missouri, North Carolina and Ohio will all hold Republican and Democratic primary elections March 15.

On the Democratic side, former Secretary of State Hillary Clinton and Vermont Sen. Bernie Sanders remain in the race, as evidenced by Sunday's night's heated debate between the two in Flint, Michigan. For Republicans, front-runner and businessman Donald Trump, Texas Sen. Ted Cruz, Florida Sen. Marco Rubio and Ohio Gov. John Kasich are still guiding their campaigns. Retired neurosurgeon Dr. Ben Carson officially dropped out of the race Friday following poor results on Super Tuesday, during which he did not win a single state.

“Even though I might be leaving the campaign trail — you know, there’s a lot of people who love me, they just won’t vote for me, but it’s OK, it’s not a problem,” he said Friday at American Conservative Union’s 2016 Political Action Conference in Maryland. “I will still continue to be heavily involved in trying to save our nation.”
