Twitter has partnered with Square to make donating to your political campaign of choice even easier. The process is pretty simple. First, the candidates will set up an account through Square Cash, and once it is verified they will be able to share a unique URL or a $Cashtag with supporters. The tweets will include a built-in contribute button, which you can click to make the contribution of choice.
Once you click the contribute button, you will be able to enter your donation amount, add your credit or debit card and other required information, and then donate. After you make your donation, you'll be able to share the candidates $Cashtag to your followers if you wish.
