For politicians it is merely a small inconvenience. They can route the limited resources to themselves and/or they can afford to pay black market prices very easily. It would be naive to hope that the blockade affects the politicians enough for them to bow to the demands made.

Who is the blockade actually affecting? 

1. Poor people who depend on daily wage to put food on the table. Poor people who lose their jobs due to industry closure - triggered by lack of fuel due to blockade. 

2. Poor people who cannot afford black market or transportation for their sick family members 

3. The protesters themselves who waste time and energy on a misguided protest. 

It's time the protesters and their supporters actually re-accessed the effectiveness and plausibility of the blockade.
