Super Tuesday: The day that makes - and breaks - future US presidents

The frustrated State Board of Elections approved the request, so voters on Tuesday will not have to sign the statement to participate in the Republican primary.

Tennessee's Presidential Preference Primary has arrived, known regionally as the "SEC Primary" and nationally as "Super Tuesday".

Donald TrumpThe U.S. presidential election is divided into two parts: primary elections, where representatives of the Republican Party and the Democratic Party choose their presidential candidates, and the national election, where the entire nation votes to choose from the designated candidates.

Splitting Tuesday's states with Clinton could keep the independent senator alive until the April 19 primary in NY, and even the California primary on June 7.

Democrats also vote in the same 11 states as Republicans, plus Colorado and American Samoa.

Both Democrat and Republican primaries: Alabama, Arkansas, Georgia, Massachusetts, Minnesota, Oklahoma, Tennessee, Texas, Vermont and Virginia. The state awards 32 delegates in the Democratic race, and 40 delegates in the Republican race. The first caucus was held in Iowa on February 1, and the last primary will be held on June 14 in Washington, D.C. In July, delegates to the Democratic National Convention will elect our party's nominee.

However, both still face strong contenders within their own party that can pose a challenge to their presidential bids. The Democrats have no such majority-takes-all rule, so a candidate who gets a majority of the vote still will not win all of the delegates as long as at least one other candidate meets the 15% threshold. The Trump-Cruz-Rubio wrangle in the top Republican race and the Sanders-Clinton rumble on the Democratic side don't mean as much by the time voters reach legislative races. Clear frontrunners will likely emerge, and a couple of Republican candidates may drop out if they fail to gain traction, namely Ohio Governor John Kasich and neurosurgeon Ben Carson, who are trailing their rivals by big margins in the polls. The Secretary of State's office warned that results for presidential delegate candidates will be reported last and may not be available until Wednesday, March 2. Texas is the largest and most important battleground for Republicans on Tuesday, with 155 delegates at stake. This difference suggests that there remains a real, albeit far from overwhelming, possibility that another candidate may win the nomination (these forecasters give Marco Rubio a 25 percent chance).

Live coverage of the the Super Tuesday election results can also be found below. One such candidate whose name comes to the mind immediately is none other than President Barack Obama who lost to Hillary Clinton in Super Tuesday eight years ago. As Trump has continued to surge, a movement has begun growing within the Republican Party to stop him.
