According to the US Constitution, a Presidential candidate must be a natural born citizen of the United States, a resident for 14 years, and 35 years of age or older although being male and white also seems to help but where the UK Elections is all done and dusted within 10 weeks, the run for the 2020 American Election has begun already with 20 Democratic candidates holding the first debates and Donald Trump has launched his (hopefully unsuccessful) re-election bid.
Most candidates running for office usually have a background in politics and have held an elected position, like senator, governor, vice-president, or member of Congress and most modern candidates hold university degrees and over half the former US Presidents graduated in law.
The US has never elected a non-Christian or a woman and only one President, Barack Obama, has not been white.
Becoming President - or even trying to be - can be eye-wateringly expensive. The ability to raise funds from your supporters, or spend your own cash, is of the utmost importance as the 2016 election cost a combined £1.8bn according to campaign finance watchdog OpenSecrets.org.
You need to be in one of the main two parties of either the Democrats or the Republicans but even winning the most votes might not ensure you get to place yourself in Donald Trump's reinforced chairs butt groove because Al Gore in 2000 and Hillary Clinton in 2016 gained the most votes but found themselves watching someone else go by in the Presidential Limo.
There are far too many Democrats to even consider looking at them just yet so we will let them be whittled down and anyway we have our own Government to worry about and if, as expected its Boris Johnson, we could well be America's 51st State by then so we will get a vote anyway.
