You're talking about two different things.
Both parties hire companies, or sponsor groups, to try to sign up unregistered people in areas where they think the result would be more new voters in their favor than the opposition. It's a reasonable tactic and in general good for the country to increase participation. I don't think either party should be blamed for trying to do this.

The problem is the people hired to do this sometimes are paid by the head count, but at least get paid to produce... that invites cheating. Over zealous volunteers, have the same temptation. This is bad because it's a waste of the taxpayers money when the lists are faked.

The safety net is supposed to be the election officials that verify and validate the lists the hunter/gatherers turn in. This is the point where it becomes a big problem if the officials are sloppy, bias, or down right dishonest.

In order to blame the republicans in this case, even if they told the company to only sign up Republicans, (which doesn't seem the case), they are only guilty if they are colluding with the election officials to disqualify valid voters or qualify ineligible voters, (which doesn't seem to be the case either). Like the big brouhaha about Acorn, it's political mudslinging. The ones we have to keep an eye on is the election officials.

Everyone I meet, has some anecdotal evidence about dead voters voting and multiple voting for fun & profit, but there doesn't seem to be much hard evidence of that. Saying they did a check of the voter registration rolls and found X number of dead people, doesn't mean they voted. As a matter of fact, with turnouts south of 60% at best, and usually less than 40%, it's a pretty good bet they didn't.
