When Obama and Biden won re-election in 2012, defeating a Mitt Romney-Paul Ryan ticket, the Republicans lost seven seats in the House in the November congressional elections, but still retained control of that chamber. However, Republicans were not able to gain control of the Senate, continuing their minority status with a net loss of two seats. In the aftermath of the loss, some prominent Republicans spoke out against their own party. A post-2012 post-mortem report by the Republican Party concluded that the party needed to do more on the national level to attract votes from minorities and young voters. In March 2013, National Committee Chairman Reince Priebus gave a stinging report on the party's electoral failures in 2012, calling on Republicans to reinvent themselves and officially endorse immigration reform. He said: "There's no one reason we lost. Our message was weak; our ground game was insufficient; we weren't inclusive; we were behind in both data and digital, and our primary and debate process needed improvement." He proposed 219 reforms that included a $10 million marketing campaign to reach women, minorities and gays as well as setting a shorter, more controlled primary season and creating better data collection facilities.
