MP ki kom poriyache ? Short supply of MPs

With political uncertainity in Delhi, guess who is making most out of it. Some MPs, we never heard name or as a matter of fact who never raised their voice in parliament, have become real assets in the Delhi bazar. If what NDTV reported, is to be believed, rate of "free" MPs have suddenly shoot to an average 25 crore (Rs). From last few days, one question is peeping into my mind. Why MP buying/selling is called horse trading? Any one ?


NB:
In '93, congress govt was accused of buying 10 jarkhand MPs for an undisclosed sum. One of JMM leader Suraj Mandal said -
''We did not take money. We only took donation. Even those who are taking money today will take as donation for the party''.
