A promising bill to boost voter participation among college students passed the Illinois Senate last Thursday. Unfortunately, that's probably as far as it's going to get. As with most proposals to make it easier for citizens to register to vote, Republicans oppose the measure, citing concerns about the cost to county clerks and the potential for "voter irregularities." They even found a sneaky way to stop the bill in its tracks.  A while back, State Rep. Chapin Rose (R-Mahomet) quietly signed on as its chief sponsor in the House.  And his sole purpose is to bury the legislation.
