DENVER (AP) -- Republican election officials who promised to root out voter fraud so far are finding little evidence of a widespread problem.

State officials in key presidential battleground states have found just a tiny fraction of the illegal voters they initially suspected.

Searches of voter lists in crucial swing states from Colorado and Florida have yielded numbers of ineligible voters that amount to less than one-tenth of 1 percent of all registered voters in either state.

Democrats argue that the searches waste time and, worse, could disenfranchise eligible voters who are swept up in the checks.

Republicans contend that voting fraud is no small affair, even if there are few cases, especially when some elections are decided by hundreds of votes.
