Any presidential candidate needs money to fundraise their own campaign because of the Federal Election Commission (FEC) monthly deadline. Although Marco Rubio spent less money when compared to his opponent Val Demings in 2022, Rubio still won. In the same way, Biden can win with less money, but Biden, like any other presidential candidate, needs money to fundraise their Federal Election Commission (FEC) monthly deadline.

I was going to vote for Trump this year (I didn't vote for him in both 2016 and 2020, not even in the primaries), but I voted Nikki Haley in the 2024 primary instead, and I'm voting for Biden this November.
Some people don't want Trump for president because of his status as the nation's first convicted felon who served as President, and some people don't want Biden for president either because of his pro-Israel response to the war in the Gaza Strip.
