Needed

Isn't an opposition supposed to oppose?
To disagree, to sometimes propose
An alternative way, a different route
And sometimes, when needed, to stick in the boot

To stand up for those who didn't vote for the victor
To show how the policy can be both looser and stricter
Not simply to abstain, or acquiesce
Bu when needed, to shout, and make a protest

They don't have to be at odds with everything said
But neither to jump in and share the same bed
Those wielding power have an obligation
While opposition is needed for the good of the nation
