More than 25 challenges to Arizona candidates’ petition signatures were filed before yesterday’s deadline in races for governor, legislature and Congress.

In some cases, candidates have already withdrawn. In others, a judge will have to sort out if signatures are, in fact, valid, and if not, whether a candidate still has enough signatures to qualify for the ballot after the invalid ones are thrown out.

On The Show to talk through some of the races that could be affected was Jeremy Duda of The Arizona Capitol Times.
