It doesn't really matter whether it's a Democrat or not. As you note, it's the liberal causes that they are championing.
For example, the MSM was pretty quiet about GWB opening up the US banking and housing market to Mexican illegal aliens.
They were also equally quiet when he signed the Social Security Totalization Agreement with Mexico that would allow Mexican illegal aliens to apply for, and receive US Social Security benefits for the time they worked here illegally.
There has to be a way to publicise increasing liberal corruption in a manner that will catch the attention of the electorate.
