You've missed the point entirely, on purpose I imagine. The impact of Citizens United is primarily with regard to corporate lobbying, not campaign contributions. Super PACs, the biggest travesty to come out of Citizens United, explicitly CANNOT contribute to election campaigns or specific parties.

Citizens United is especially relevant to presidential elections -- it arose directly out of the 2004 and 2008 campaigns.
"The conservative non-profit organization Citizens United wanted to air a film critical of Hillary Clinton and to advertise the film during television broadcasts, which was a violation of the 2002 Bipartisan Campaign Reform Act, commonly known as the McCain–Feingold Act..." [1]
In other words, you are wrong about Citizens United, and unpleasant about it.
