Answer
In 2012, Kathy Hochul was defeated for re-election by Chris Collins, who won 54.4% of the vote to Hochul's 45.6%. This was a major upset, as Hochul had been considered a strong incumbent and had won her previous election by a wide margin. Collins' victory was attributed to a number of factors, including his strong support from the Tea Party movement and his ability to raise more money than Hochul.
