Primary watch: Utah voter turnout under 20%, candidate accused of breaking rules

Key Points:

• As of Monday morning, 19.4% of Utah voters had cast ballots ahead of Tuesday's primary election, with turnout expected to rise to the mid-30% range by polls closing.
• Utah has no primary races for governor or U.S. Senate this year, but three of four congressional districts are holding primaries following recent redistricting.
• Controversy arose in the 2nd Congressional District over postcards sent by Rep. Blake Moore's office, which opponents claim violate rules on unsolicited mass mailings; Moore's office maintains the mailers comply with regulations by sending fewer than 500 pieces per batch.
• Moore's primary challenger, State Rep. Karianne Lisonbee, vows to propose legislation to close what she calls a loophole allowing members of Congress to use taxpayer funds for self-promotion.
• Voters are advised to submit primary ballots by 8 p.m. Tuesday via drop boxes, official polling locations, or in person rather than mailing them at this late stage.
