Politics of Convenience!

Hi Friends,
When I was in my high school I used to find politics very "boring". I always thought what is the fun in knowing which minister is doing what, how many children Lalu has, why politics is called a "dirty game".....
But over the period of time as I started waking upto the realitites of life I came to know that Politics affects the common man from all quarters in a democratic country( Thats what we "proudly" call ourselves..) . And quite interestingly I started "enjoying" the twists and turns of this never ending soap opera.
Well we are witnessing another episode of melodramatic Politics these days. Left has "finally" stood upto its threat and has actually taken the suppport back from the govt. Left says that it has real concerns over the Nuclear deal with US, so it's taking the support back on "moral grounds". So far so good. But in the meanwhile govt has found new allies in Samajwadi party and others.... Congress is quite confident of getting the vote of confidence on July 22nd(ie the scheduled date) and no points for guessing that it will get that in most probability.

Now the real question arises that why Left parties took so long to withdraw their support. When the whole world knew that govt was going ahead with the deal and looking for support from all possible quarters, why did left gave the chance to the govt to get enough allies which can sustain the govt even without Left's support?
...now when govt will get the vote of confidence they will be able to get the deal through anyways. So what was the fun of showing the "morality" to the nation at a wrong and delayed time.

So is it really that Left is opposing the govt?.... or has it actully given enough time to govt to save itself and the deal??

Well I couldn't understand at first why they call politics a "dirty game", I think I am getting to know it a little better now. Do you?
