“Democratic government is legitimate government”?

“Democratic government is legitimate government”? Support the statement with arguments.

Democratic government is a legitimate government: It may be slow, less efficient, not always very responsive or clean. But a democratic government is peoples’ own government. That is why there is an overwhelming support for the idea of democracy all over the world. People wished to be ruled by representatives elected by them. They also believe that democracy is suitable for their country. Democracy’s ability to generate its own support is itself an outcome that cannot be ignored.
