According to Federal Election Records found on OpenSecrets.org for the election year 2000 the NEA donated
$2,691,678 of which 92% of the recipients were Democrats.
Moreover, if CFR (campaign finance reform) were passed only unions would be able to advertise for their candidates and/or political ideologies in the 60 day period prior to an election. Non-unions would be excluded.
They do more than donate directly. They conduct a number of activities that directly benefit the RATS.
Marsha, can you share some of their activities?
