From Maine all the way to Nevada, primary voters across the country finalized several key general-election matchups on Tuesday.
In Virginia, former Gov. George Allen won his state's primary, earning another shot at the Senate seat he once held.
After defeating several Tea Party candidates, Allen will now battle former Democratic Gov. Tim Kaine in November.
In North Dakota, there was a Senate primary but also a battle over whether to eliminate local property taxes.
Opponents of the tax argued it defeats the principle of property ownership since the government could kick residents off their own property for not paying the tax.
In the end, the measure was rejected by voters, with the majority concluding that while property taxes are high, eliminating them altogether was not the solution.
Giffords Aide Wins AZ Race
Of all the races Tuesday, Arizona's special election to fill the seat of former Rep. Gabrielle Giffords was the most closely watched -- not only because of the congresswoman's tragic shooting two years ago but also because keeping that seat is important for Democrats if they want to regain control of the House.
"Each party's hungry in June to have a story of winning and victory to sell to the American public as they head into the fall campaign season," Yahoo! News Washington Bureau Chief David Chalian explained.
Democratic candidate Ron Barber defeated Republican challenger Jesse Kelly. Barber, a former aide to Giffords, was also wounded in the January 2011 shooting.
"Thank you Gabby for everything, everything you have done for us, and will still do for us," Barber said during his acceptance speech.
All of Tuesday's races add momentum to both Democrats and Republicans as they look ahead to the November elections.
Meanwhile, campaign season is in full swing for both President Obama and GOP presidential nominee Mitt Romney.
Obama appeared at a campaign rally in Baltimore, urging voters that his second term would keep moving the country forward. Romney has been ramping up his campaign in Florida, a key state in the general elections.
