It can be said that financial strength is also an important criterion for measuring whether a candidate possesses sufficient capacity!
This is common in Western countries; just look at the General Elections in the United States these years, where the invested funds have become increasingly outrageous!
However, in Russia, participating in the General Elections doesn't require spending too much money.
Like last year's election, as far as Wang Ye knew, Khodorkovsky and his father-in-law didn't spend much money—in the final stage of the election, both sides only invested a couple of hundred million US dollars each.
Of course, this was also because Khodorkovsky, at Wang Ye's persuasion, gave up in the final moments and didn't struggle to the end.
By the next election four years later, the election funds needed by Medvedev wouldn't be too exaggerated, as there wouldn't be any strong rivals to compete against him by then.
