Invalid vote button on voting machine needed

When one looks at the list of candidates of most of the national parties it can be seen that many criminals have crept into it. The criminal politicians have destroyed Indian democracy. As many of the MPs have deceived the common people the call-back option, as pointed out by many wise thinking people, should be made available by a law so that non-performing MPs can be recalled by voters. An ‘invalid vote-button’ must be invariably put on all voting machines so that voters could keep out from casting votes if all the contestants are with criminal background. Keeping away from polling booth is quite different from that of using an invalid vote button.
