Uh, no. Citizens United was about actual speech (a political movie), not money. It doesn't allow corporations to make political contributions, it says that they can't be prevented from spending money to present particular points of view.
For example, take the Google, Microsoft, etc, NYT full page ad opposing NSA spying. That's precisely what Citizens United protects.
