Senator Jeff Merkley (D–OR), who has been working with Sen. Charles Schumer (D-NY) on a comprehensive immigration bill, does not expect action on immigration reform this year, according to The Hill. The senator’s statement exemplifies the on-again, off-again relationship that legislators have with immigration reform. Below is a brief recap of comprehensive immigration reform developments so far in 2010:

• February: Although immigration reform was a staple of President Obama’s campaign and early-term rhetoric, his State of the Union Address contained only one sentence on the topic.
• March: Senators Schumer and Lindsey Graham (R–SC) unveiled their “blueprint” for comprehensive reform.
• April: Senate Majority Leader Harry Reid (D–NV) predicted that the issue would not be addressed until after Memorial Day.
• June: President Obama urged Republicans to work with Democrats to pass a bill.
• July: In a keynote speech at American University’s School of International Service, President Obama pressed for immigration reform.
• August: A spokesperson for Senator Dick Durbin (D–IL), who introduced the Development, Relief and Education for Alien Minors Act (the "DREAM Act") (pdf), legislation to help students who immigrated to the U.S. as children obtain citizenship, reportedly said that comprehensive immigration reform is still possible in 2010.

Meanwhile, some state and local governments have attempted to fill the void they believe is created by federal inactivity on immigration reform, with Arizona attracting the most attention.
