Good for you.
"History since 1976 has shown us that if the candidate is not the incumbent president, unless the incumbent President is serving his second term, if the said candidate wins the Iowa Caucus for his party, he USUALLY does not win his party's nomination but NEVER becomes President of the United States.
Since 1976, only two candidates who won the Iowa Caucus for their parties ever became the President of the United States. They were George W. Bush in 2000, and Barack Obama in 2008; however, had either of the incumbent presidents, Bill Clinton or President Bush, respectively, not been serving their second terms, neither Candidate Bush nor Barack Obama would have won their general elections for the President of the United States, history shows."
2012 Iowa Republican Caucus winner won't become president, history shows
And congressmen don’t become president.
