Riginslinger - " I'd like to see and end to "birthrigh citizenship," so there'd be fewer legal Hispanics, but a citizen has the right to vote. I wouldn't quibble with that."

Maybe you wouldn't, Rig, but a major election strategy on the part of the Republican party in areas where voters tend overwhelmingly to vote Democratic has been (and continues to be) to drive down the numbers of people voting.    Republican strategists have, in fact, been pretty open about that; in general, the larger the turnout for an election, the better it is for the Republicans, since there are more low-income and minority voters than there are middle-and-upper-income whites. Purging voter rolls in a manner like ocean trawl-netting -- where many legal voters are purged along with the possibly non-legal ones -- has been used in a number of locations (most notably in Florida in 2000).   But other measures such as putting too few voting machines in lower-income or minority precincts, overuse of "challenges" at the polls to intimidate would-be voters and make the wait in line longer for everyone, have a similar effect.   

It's quite understandable that a party would prefer it if people who tended to vote for some other party would stay home and not vote.    But if that goal is pursued by unreasonable purging of voter rolls close to an election (too late for those unjustly purged to rectify the situation) or by excessive an selective "challenges" to minority voters, etc., it's not ethical or fair.
