2. The primary goal of Republicans in congress is to block anything Obama supports, even when it is their own idea or legislation that will help the American people.
From the very beginning of the Obama administration, as discussed in a Republican strategy meeting on the night of Obama’s 2009 inauguration, Republicans planned to “Show united and unyielding opposition to the president’s economic policies.” (source; see also: Do Not Ask What Good We Do: Inside the U.S. House of Representatives, by Robert Draper). In an October 2010 interview with National Journal, Republican senate minority leader Mitch McConnell said: “The single most important thing we want to achieve is for Obama to be one-term president.”
From “The Price of Politics,” by Bob Woodward: “Boehner knew that the predominant school of thought in the conservative movement held that you shouldn’t ever negotiate with Obama…Boehner realized that doing a deal with Obama would put his speakership in jeopardy, and didn’t want to take the risk” (pp.181-183).
Record-setting Obstruction:
- Blocked Nominees: There are still over 100 unconfirmed Obama nomination because Republicans have blocked them: http://www.businessweek.com/magazine/obamas-legion-of-unconfirmed-nominees-01122012.html; http://www.whitehouse.gov/briefing-room/nominations-and-appointments


- Opposing their own ideas once Obama embraces those ideas
“Seven Republican co-sponsors of a Senate resolution to create a debt-reduction panel voted in January 2010 against their own resolution, solely to keep it from getting to the 60-vote threshold Republicans demanded and thus denying the president a seeming victory.” (Source: http://articles.washingtonpost.com/2012-04-27/opinions/35453898_1_republican-party-party-moves-democratic-party)

- Record-setting use of filibuster
As far back as January 2007, Senate Minority Leader Mitch McConnell made it clear that he would assume the role of Senate Obstruction Leader by insisting on a 60-vote supermajority, rather than a simple 50-vote majority, for getting bills through the Senate.
He claims “that’s the ordinary procedure.” But he’s wrong, and we have the proof. The reality is, his abuse of Senate procedures to block the majority will on legislation is unprecedented. McConnell and Senate Republicans like the filibuster now, but they didn’t when Democrats used it more sparingly in the 109th Congress against President Bush’s most extreme judicial nominees (source).
