Paragraph #1 - Describe how a president is elected.

Paragraph #2 - Describe who might have a difficult time being elected with how much money and time it takes.

The way a president gets elected is by creating an exploratory committee which you raise money for the primaries. Than they must announce it and start getting signatures from fifty states. So they can get their name on a ballot. This usually happens a year before the election. Each party has a season when they campaign, like t.v ads in important states. The first real primary occurs in Iowa than New Hampshire a week later.
After the primaries are done we usually know who will be the republican and the democrat. Between February and November the candidates participate in debates. Finally in mid November the elections are held. The popular vote does not determine who wins it's decided by the Electoral College.

It will be more of a challenge to get elected if you lack money. Which means you can't campaign as much as the others. So you have to have millions and millions of dollars raised. You have to dedicate an entire year for campaigning. Which means no working and mostly traveling. You have to have a lot of time on your hands and be committed a 100%.
