Honest question, if Bernie is getting crushed in the primaries in my state, should I even vote?

Don't hurt me, this maybe be naive but I'm honestly wondering. According to polls he's getting destroyed in my state. Now I'm still all for him and still spreading the love, but is there any point in voting if the numbers are so staggering against him? Or am I missing something (aka the numbers dont tell the whole story)?And yes, i know its my right and responsibility as a US citizen to do so, but thats not what Im asking. Thanks peeps
