US business magnate Michael Bloomberg is mulling an independent bid for the White House. This is big news in US politics. As the 14th-wealthiest person in the world, as well as the founder and CEO of Bloomberg L.P., Bloomberg has strong power to mobilize public opinion. Once he decides to throw his hat into the presidential race, it will add a new wrinkle to a topsy-turvy race for the White House.

With billionaire Republican frontrunner Donald Trump and Hillary Clinton, who is from the wealthy Clinton family, already in the race, Bloomberg's candidacy, if declared, will reinforce people's impression that the US election is a game of the rich and capital. Complaints have been triggered about the active role that the Clinton and Bush families have long-played in US elections. Critics dwell upon the "money politics," while some others believe there is no need to make a fuss, since the well-designed US political system will counterbalance the influence that money has upon it. The truth is that money is not omnipotent in an election, but it is indispensable. 

Nowadays, the basic principles for democracy have been deeply rooted among the people across the world. Even in societies which have not adopted a Western-style multi-party system, the spirit of democracy has permeated into political governance by other forms.

Proud of their achievements in the past century, the West deems incorporating democracy with the Western-style system as common sense. However, since entering the new century, the multi-party system has encountered many problems. Questions over the system have emerged with the political effectiveness of some traditional Western countries being dampened by partisan struggles. Some say China has become more like a "capitalist country" as an increasing number of capitalists have appeared in China. Compared with the situation in the US, capital does not exert the same influence in China as in the US. Capital dominates everything in the US. The US political system must conform to the interests of capitalists.

Any system, no matter how reasonable it is at the beginning of its formation, may become alienated from the new times and therefore reforms must be launched to revitalize it. A candidate like Trump leading all other Republican presidential runners is a sign of a problem in the US election system. It is revealed that Bloomberg is considering throwing $1 billion of his vast fortune into challenging the Democrats and Republicans. This serves to remind people of the supreme dominance of capital in US politics.
