Republican Mark Amodei and Democrat Kate Marshall released dueling TV ads this week, their closing salvo in Nevada’s 2nd district special election.

Marshall, who needs a strong showing from Democrats on Election Day to have a chance of winning, launched an ad Tuesday that goes squarely after Amodei, accusing him of abusing “power for personal gain” and supporting tax breaks for millionaires and an end to Medicare.

Early-voting turnout tallies indicate Amodei has a sizable advantage, as Republicans account for 20 percent more of early voters than Democrats. The edge is evident in his last ad, which is a traditional positive spot.

While Marshall has outraised him, Amodei has received assistance from organizations including the National Republican Congressional Committee and American Crossroads. Marshall has received no help from the Democratic Congressional Campaign Committee, but she received a late endorsement Wednesday from the Blue Dog Coalition political action committee.

Reps. Dennis Cardoza (D-Calif.) and Jim Matheson (D-Utah) said on a conference call that they would have liked to see the DCCC spend money on the race.

The Blue Dog’s PAC gave her a $5,000 check this month, as did NARAL Pro-Choice America PAC. House Minority Whip Steny Hoyer (D-Md.), who campaigned with her in the district last week, gave her $2,000, and Rep. Allyson Schwartz (Pa.), chairwoman of the DCCC’s recruiting and candidate services, gave $1,000 through her We the People PAC.
