Could a sudden death decide the next president?

In the US the people get to choose who their party's candidate is going to be for the presidential election, to be held in November. So, in effect they get to choose twice - first a candidate for each of the 2 parties and then the president out of the two. States hold primaries to decide who they want as their candidate and each primary is preceded by a debate. South Carolina is to hold its primary on 20 February for the Republicans and on 27 February for the Democrats. Two contenders, Chris Christie and Carly Fiorina dropped out of the Republican race after the New Hampshire primary, leaving 6 still standing. A majority of viewers thought that Marco Rubio won the debate in SC, With Donald Trump coming second and Ted Cruz third. The Republican establishment would prefer Rubio to be their candidate so they are frustrated that even though Trump was attacked hard during the debate his popularity remains undiminished. Trump is a clear favorite for the SC primary with polls projecting 35-42% of votes, with Ted Cruz coming second. Why are Trump and Cruz giving heebie jeebies to the Republican Party? Because they feel that if either of them goes on to become the candidate then Republicans will lose down-ballot races. Down-ballot races mean, elections for the entire 435 seats for the House of Representatives, 34 seats in the Senate and governors in 12 states. The liberal media is gloating that Jeb Bush, brother of the previous President, George W, is way down in the polls. They see George W as " arrogant, dishonest and not very bright ". " He was infuriating because his life was a string of undeserved wins, from college admissions to presidential elections," they say. As for Trump, they label him as " ill-informed, inexperienced, bigoted, sexist xenophobe ". Therein lies the problem. They seem to have an utter contempt for the voters, and, hence, for the democratic process. On the Democrat side Hillary Clinton got thumped by Bernie Sanders in New Hampshire after scraping through in Iowa on the toss of a coin. Her biggest problem is that she is tainted by the gasbag, Obama. She was the Secretary of State during his first term, which means that she cannot distance herself from the mess he has created all over the world, to win elections. But Obama could still have a great effect on the election if he so chooses. Antonin Scalia, a conservative judge of the Supreme Court died suddenly. The US Supreme Court has 9 judges, of whom Breyer, Ginsberg, Sotomayor and Kagan are seen as liberals, Alito, Thomas and Roberts are conservatives and Kennedy is in the middle. Obama can alter the balance by picking a liberal to replace Scalia . Republicans have sworn not to confirm anyone that Obama picks as replacement, which could set up a huge fight if Obama so chooses, forcing undecided voters to take sides. A sudden death to decide  the next president. Very interesting indeed.
