▼ The first time you picked up a crayon as a small child, you probably felt more comfortable and more natural drawing with one of your hands than the other one.
Excluding the small number of truly ambidextrous people — those who can use their right and left hands with equal ease — humans generally have a dominant hand (and side of their body) that they favor for everyday tasks.
But why is that?
Most people — about 85 to 90% — are right-handed, and there's no population on Earth where left-handers are in the majority.
That uneven split has had some historic downsides for lefties. They've had to use scissors, desks, knives and notebooks that were designed with righties in mind. Many lefties were forced, against their natural inclination, to write with their right hands (including some famous examples like King George VI of England). They've been discriminated against and eyed with suspicion, as evidenced in the language used to describe lefties. "Right" in English obviously also means "correct." The etymology of the word "sinister" can be traced back to the Latin word for "left."
While the stigma against left-handednesshas faded in most places, scientists are still confounded by the righty-lefty divide. Researchers are still trying to understand what makes people prefer one hand over the other and why righties dominate.

This is because the left half of brain deals with the logical activities and people with dominant left brain are right handed, whereas the right brain deals with creativity and the people with dominant right brain are lefty in general.

I am not entirely agreeable @Chankyapriya. now , the voting public is not always logical and they may not all be politicians -end up getting the wrong ones elected. Whereas , yes- the politicians are really "creative " guys particularly the successful ones

Irrespective, which handed you are, it always brings the dimensionality in your personal life too.
