My condolonces to you & your family for this huge loss. While the state has lost it's CM, the loss for your family is huge. In these trying times, i apologize that i need to talk about politics when it might be the farthest in your mind.
The reason why i had to interrupt your mourning is the increasing clamour to make you CM. Believe me, most of them are following the true traditions of the Congress party or trying to take advantage of the situation. A novice CM who is out of place in regional politics isn't their nightmare but their dream come true. It need not be said that your CMship will be one of the most corrupt in state history, not because you want it that way, but because you would have no control over these ravaging lunatics.
You entered politics about 6 months ago. You have been elected MP. Can you state five things you have accomplished in these 4-5 months? Politics, unfortunately, is easier spoken than acted upon. I am not denying your way to the CM post, but asking you to mature beforing seeking it. Remember that this is the last time you will get the CM post handed on a platter, you need to earn it going forward. Are you ready & prepared for it?
Putting myself into your shoes, i would do the following. If you are keen on the CM post, consult with Sonia & Rahul on the path leading to the CM post. Consult Rahul on how he got educated on people's issues. Get a mandate from Sonia that you will succeed Rosiah whenever he is ready to give up the CM post. Ideally, he should occupy the chair for 2 years and hand over to you at mid term. Take these 2 years to tour the state, tracing the same steps as your father. Learn the issues of the farmers, traders, businessmen, salaried class, working women, housewives and all. Once you attain maturity, the post is as good as yours. Remember, politics is like a bank account, you can only draw what you put in. Frankly, my dear, you haven't put in much to date. Start investing and then encash at a latter stage.
It is obvious that the support you have today will dwindle drastically as time flies, but you will be left with your core supporters and that's going to be your first lesson.
