Whakakiia te rerenga e whai ake nei: I te Hui-tanguru 3, 2008, i tautoko a Shriver i a Senator Barack Obama mo te whakaingoatanga perehitini 2008 Democratic. I whakawhiwhia te whakaaetanga ki tetahi huihuinga UCLA e whakaatu ana i a Caroline Kennedy (te whanaunga o Shriver), Oprah Winfrey, Stevie Wonder, me te wahine a Obama a Michelle Obama. I whakaaetia e te Kawana Schwarzenegger a Senator John McCain mo te tohu perehitini Republican i etahi ra i mua atu i te Hanuere 31, 2008. I muri mai i taua tau, i te tau 2004, i tae atu a Shriver ki
te Democratic National Convention i te wā i kōrero ai tōna matua keke a Ted Kennedy.
