So far in the 2010 election cycle, the CWAs political action committee has contributed $699,000 to federal candidates and spent $4 million on all federal-related activity, including donations to the party committees.
Comcasts PAC has given $991,000 to candidates and spent $2 million on
election-related activity. Democratic candidates received almost all of the unions contributions and just over half of Comcasts donations.
They both have a significant amount of money and a heck of a lot of political heft, said David Levinthal, spokesman for the Center for Responsive Politics, which tracks campaign finance issues.
