A political donor is important to politicians. Political donations have been around as long as there have been elections. They are an important and integrated part of the political process. It is not untrue to say that no candidate could effectively compete without donations. Therefore, making sure this is strategically thought and planned as close as possible. Those donations come from a variety of people and sometimes they come from businesses and organizations. All particularly devoted to the idea of pushing a person to a seat of government where they can, possibly, push for change that is something people want to see. Make no mistake about it. If you are a politician then you need the support of your voters in the form of votes and donations. Therefore, you have to set up your organization to receive these donations and support in ways that are convenient for your constituents.
If it is difficult for your people to donate then they are unlikely to try to donate to you. A problem that will leave you in a bad position when it comes to getting your message out there in the world. Luckily, you are not limited to the known big name processors. In fact, using these services is usually a bad idea for a person like you. They are bad ideas because they are not properly set up to handle a non-profit activity. Most of them work with for-profit ventures. For-profit ventures, usually, have larger margins to work with and, thus, a company processing for them can charge more. However, you need all of your donations to go to advertising your message instead of lining your processor’s pocketbooks. You do the work to find these people which means that you are doing the heavy lifting. You should get the larger share of the pie because of this fact.
A good partner in your quest for your government, local or national, seat is essential. You need one that understands that every penny counts. They should also allow you to make use of the multitude of social systems around the internet which include live streaming sites. The truth is all of them do this well and you will need to do research to make sure that the system you have in mind will do what you need it to do.
The quick answer, if you do not have another way of dealing with this, is to send everyone to a page where they can donate. You control this site and it only has to have a link active link to it from a social media system. This is, usually, possible on most systems but some like Instagram. Instagram allows one live link in the profile. You can type it out in the description or comments but you have to rely on the savviness of your reader/watcher to copy and paste it into their browser. Something that may or may not be a reasonable expectation.
Therefore, you may find a partner who can make this easier for you. You just have to ask and/or do your research ahead of time. The time you take to do this makes sure that you are capable of advertising effectively on some of these social media systems. In fact, it gives you an advantage if your opponents have not done their homework.
