A friend of mine [1] has been building something that is <i>exactly</i> what you describe: <a href="https:&#x2F;&#x2F;www.shiftspark.com&#x2F;content&#x2F;how-it-works" rel="nofollow">https:&#x2F;&#x2F;www.shiftspark.com&#x2F;content&#x2F;how-it-works</a><p><i>&quot;We allow people to speak to their politicians. And not just during campaign season. By pledging money, ShiftSpark lets you signal the issues tied to your support when politicians need it - BEFORE the election. This gives us more candidates, less corporate influence and politicians who listen.&quot;</i><p>[1] He was previously the president of the Manhattan Young Democrats and is currently a Vice President at the Young Democrats of America.
