The Iowa Caucuses help candidates gain momentum in the race. You need to have won one of the Caucuses to have a good chance of becoming president, or even the candidates. You need to win a Caucus or Primary to be able to become president. Even though you have won a Caucus, or Primary, you still may not win. They only give you a head start. If you don’t win a Caucus or Primary, funders drop out, and candidates have less of a chance of winning.

Although the New Hampshire Primary does give a head start most times the Primary winner does not become president. Only 15% of the time the winner becomes president, so New Hampshire Primary is not an accurate barometer of who will win the candidacy.

Super Tuesday is basically a day in which 12 states hold their primaries or caucuses at one time. Super Tuesday allows more things to get done by the time the elects comes in November. It speeds up the process of the state elections by giving more leeway and time for them to occur by getting twelve states done on one day.

Ted Cruz, Donald Trump and John Kassich are running on the Republican party. Hilary Clinton and Bernie Sanders are running for the Democratic party.

Donald Trump is currently leading the Democratic Party. While Hilary Clinton is currently leading the Republican Party. The current predictions impact the process because the front runners gain momentum and get media attention. The front runners are not always the winner because the runner up have won caucuses and Primary’s right along with the front runners so they still have a chance to win president.
