No because if every one has to agree with one party then there would be no reason to vote because you will not have a party to debate the issue
If there was only one house of representatives the smaller states will have less representation.
Explanation:
The original model of the house of representatives was taken from Britain. There are two senators per state and then there is the house of representatives where the number of members depends on the population of the state.
If the senate is removed, there will be less representation for the smaller states and thus there will be a chance they can be cornered.
The issue with this, is that constitutionally, all states are to be equal in the eyes of the federal government in the Federation.
