I repeat, most of the money allocated to Congress goes to taking care of constituent problems and communications. How much do you think it should take to do customer service for 500,000+ people. I have a staff of 1 to take care of about 400 customers and we can barely keep up. Again, give us examples of actual Congress people that are misusing their funds.
Oh and yes, they are not in session half the year - more so since the Republicans took over and decided they didn't want to get anything done - however, don't think that they all spend that time sipping lattes or tanning at the pool. Most have to use that time raising money for their next campaign and attending political meetings and fundraisers at all hours when they are not meeting with disgruntled constituents. No matter whether you like it or not, it's work, and a large part of their jobs.
