Lawmakers are scheduled to attend more than 135 holiday parties that are also campaign fundraisers in December, Sunlight Foundation's Political Party Time reports.

A year ago, there were only 38 holiday party/campaign fundraisers scheduled during December, the site says. That number was probably low because of the recession and it was only a few weeks after the Presidential election where historic sums of money were raised and people were suffering from donor fatigue.

The key to holiday parties that are also fundraisers is that the lobbying gift ban rules don't apply. Lobbyists can host and attend parties for lawmakers as long as they are fundraisers.

Among lawmakers to be feted at these parties are Rep. Mazie Hirono, D, Hawaii, Senate Majority Leader Harry Reid, D-Nev. and Rep. Carolyn Maloney, D-N.Y.
