Generate text that refutes this claim: Parties as coalitions  The two political parties are ideologically broad churches, with many different factions that stand up for varying positions on the ideological spectrum. The republicans for example contain within them several different republican movements; from social conservatives or ‘the religious right’, through libertarian conservatism like much of the tea party, to fiscal conservatives who are mostly more moderate. Interweaving these three is national security conservatism and issues conservatism. [1]  Policies formed by each party are specifically designed to take into account of the different strands within the party, creating a platform that all candidates can stand on.  The policy is in effect a compromise between different wings of the party, with Primaries adding credence to a particular view.  In effect, Policies enacted under Single-Party Government have had the oversight from party members in order to be representative of the different interests within the party, thus delivering clear, coherent policies to the people that are constantly self-corrected due to the different ideological streams.

The parties may be broad churches with many mechanisms in place to form the ‘best policy’ but that can still lead to flaws under a single-party government. It is easy for one wing to dominate a party, as has been seen recently with the dominance of the Tea Party within the Republican Party.  Primaries are a symptom of this, with the views of grass roots being expressed in results that do not conform to the views of a majority of voters.  This can lead to parties standing and governing on a platform that is unrepresentative of the aims of many Americans. Under Single-Party Government, there is little scope for moderating highly ideological government, thus underlining the need for divided government.
