The 2012 Senate elections occurred during the 2012 general re-election of President Barack Obama against challenger Mitt Romney. There were many vulnerable Democrats up for re-election in states where their party had done very poorly in 2010's tea-party fervor. However because of high turnout for the presidential ticket and the abysmally poor quality of Republican senate candidates, the Democrats instead ended up increasing their senate majority.
