The other problem is that you have to have “a reason” to challenge the registration, …

It seems that you do not have to have a sound or valid reason:

“There seems to be some inconsistencies with how challenges are sustained or denied, and we want to codify the fact that there are only a very limited number of reasons to sustain a challenge,” said state Sen. Max Burns, a Republican who authored both SB 202 and SB 189, at a March committee meeting where the voter challenge language was workshopped.

The resulting legislation, however, did the exact opposite. It listed some criteria that election board members may consider when receiving a challenge, such as knowledge that a voter had passed away. But it also failed to place any restrictions on what evidence activists may submit when questioning fellow voters, how many challenges one person can submit at once, or even mandate that they be residents of the state, prompting outcry from Democrats.
