If only it were that simple. The Democratic Party is a coalition party. It why votes can be pealed away in congress.
The Republican Party is 90% white and it's very difficult to peal away any votes. You just can't talk about the two parties as if they were the same. The fact that the Republican Party is 90% white, mostly Christian and centered in the deep south makes all the difference.
Reality check you ******* dumb ass. From 1952 until 1994 the US House was nearly continuously controlled by the Democrats with I think 2 2 year periods where Republicans had a small lead.
During the same period the Senate also was controlled by the Democrats. The problems we have NOW can be laid directly at the feet of the Democratic party. The deficit and the lack of regulation of Business that lead to an economic melt down. The destruction of the Public education system, the Courts usurping Congressional powers, the creation of life dulling money sucking social programs that are bankrupting this Country.
The Republicans fucked up from 96 to 2006 they did not use their majority to fix problems and added to the deficit. However the only period of time that the Government had nearly no deficit spending was during the time Republicans controlled both Houses of Congress.
