CNN projection: Gov. Tim Kaine wins
Allen conceded in a Tuesday night speech and pledged his support to Kaine.
"I congratulated him and pledged my support and cooperation as he undertakes the solemn vows of representing the people of Virginia during very difficult times in our nation's history," Allen said. "We haven't succeeded my friends in winning this election."
The race pitted two former Virginia governors against one another and each pulled from their experience in the state house throughout the race.
Though, Kaine linked himself to Obama and the president's campaigning in Virginia, he also painted himself as someone who had worked with both Democrats and Republicans. Allen, however, tried to turn that link against Kaine - tying him to Obama and the Democratic Party, where the former democratic governor served as chairman.
Making that case was costly. When outside and candidate spending was added together, the Kaine-Allen race was the most expensive race in the country. Outside groups, on their own totaled over $50 million, according to the Center for Responsive Politics.
Wisconsin: Rep. Tammy Baldwin (D) vs. former Gov. Tommy Thompson (R)
Open seat -- Sen. Herb Kohl (D) is retiring
Former Gov. Tommy Thompson won a tough Republican primary to take on seven-term Democratic Rep. Tammy Baldwin for retiring incumbent Herb Kohl's Senate seat. Thompson's attacks on Baldwin as being too liberal haven't had the impact he was hoping. The polls were very close, but Baldwin pulled slightly ahead recently, though not outside the margin of error.
Unless vice presidential candidate and native son Paul Ryan brings out strong turnout for the party, the state's historic Democratic tilt in presidential elections could help Baldwin succeed to becoming the first openly gay senator.
