Democrats argue that such provisions have the effect of disenfranchising minorities , young people and the poor , who are more likely to lack suitable id than other groups ( and who mostly vote for them ) .
Disenfranchising the punters would not only give investors an incentive to hang onto their shares for longer , the argument runs , but would also encourage those with voting rights to use them , as they would know their votes would be more likely to count in board elections and so forth .
