Below are the 10 most generous contributors to political campaigns from 1990-2006, according to the most recent data from the Center for Responsive Politics (OpenSecrets.org). Also given are the percentages of those contributions that went to Democrats and Republicans. (Information on contributions to 2008 presidential candidates is not yet available for all organizations.) The organizations themselves did not donate, rather the money came from the organizations’ PACs, individual members or employees or owners, and those individuals’ immediate families.

I did a little number crunching .
In the Totals for 1990-2006, a total of $290,399,724.45 was given to the Democrats and Republicans by these top 10 contributors. However, as noted “The organizations themselves did not donate, rather the money came from the organizations’ PACs, individual members or employees or owners, and those individuals’ immediate families.”
Of this 290 million plus dollars, $231,565,499.50 (80%) was given to the Democrats while $58,834,224.95 (20%) was given to the Republicans.
The biggest contributor to the Democrats was $37,899,980.02 by American Federation of State, County & Municipal Employees. The biggest contributor to the Republicans was $21,322,613.76 by AT&T Inc.
