A new poll shows that Democratic candidate Paul Penzone is closing in on current Maricopa County Sheriff Joe Arpaio.
The poll of likely voters showed Arpaio with 46.8 percent of the vote and Penzone with 42.1 percent. A little under 8 percent said they were not thinking of voting for either candidate.
A similar poll conducted last month showed Arpaio with 44.5 percent of voters and Penzone with just 39 percent.
The poll sample of 494 likely voters consisted of Republicans (37.9 percent), Democrats (28.3 percent), Independent (30.2 percent) and Other (3.6 percent) voters, who were all asked to identify their affiliation.
The poll was conducted by SWITCHBOARD Communications, a Washington D.C.-based firm and has a +/-4.4 percent margin of error.
