Yes. The ability to campaign effectively is directly related to how much money the political candidate has in the depths of his or her campaign bank account. It takes massive amounts of money to buy signs, television advertisements, and radio advertisements. Also, just the campaign trail alone creates a huge expense with regard to just traveling from one place to another. Money plays a key role in winning any political election.
Let's face it, money in this society is almost always equal to power. If a candidate wants to run a successful campaign, money is always necessary. Television ads, travel costs, employment of campaign helpers, etc. all cost money. If any of these things are missing, the campaign could end up disastrous.
