Does one political party spend more money on canpaigns then others explain

It is not a specific party that might spend more, but more of which person is running.

For example: If there was a candidate that was extremely wealthy and was running as a democrate, then they would invest more money in there campaign then the other party if the other party isn't as wealthy.

In other words: There is not one specific party that spends more money.

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
