(Image source: Mother Jones ) BY NATHAN BYRNE AND CHRISTINA HARTMAN ANCHOR KATIE BRENNAN Senators on both sides of the aisle have agreed on a four-page document overhauling immigration. Though Democrats and Republicans are on the same page now, NBC’s Tracie Potts says the current version of the proposal is far from final . She lays out what’s on the list right now. “Border patrols, employer verification, a guest worker program, green cards for math and science grads, and a path to citizenship for illegal immigrants.” How did a deal like this get done? The New York Times’ Julia Preston credits the incorporation of the Democratic insistence on a comprehensive bill that wouldn’t eventually deny citizenship with the Republican demand for strong border enforcement. As for the political timing of the announcement — it comes just before President Obama headed to Las Vegas to speak about immigration reform. [Video: WJLA ] A Los Angeles Times report says that trip has a deeper purpose, though — indicating President Obama is on a mission to “bequeath to fellow Democrats … a solid electoral college base rooted in the West … ” And Republicans — they had a plan of their own. Fox News’ Bill Hemmer offered some insight on Don Imus’ show Monday morning . “I think this is going to get real legs and push through. Especially because Marco Rubio’s in on this. The Republicans, before the election, they said, if you go immigration reform, you better believe we’re going to have our fingerprints all over it.” In 2007, a bipartisan effort couldn’t get enough support from Republicans in the Senate — but after President Obama took more than 70 percent of the Latino vote this past election — Arizona Republican John McCain told ABC’s “This Week” he thinks “the time is right.” SEN. MCCAIN: “We can’t go on forever with 11 million people living in this country in the shadows in illegal status … Believe it or not, I see some glimmer of bipartisanship out there.” And it’s a priority of President Obama’s — as evidenced by this from his inaugural speech: “Our journey is not complete until we find a better way to weapon the striving, hopeful immigrants who still see America as a land of opportunity.” [Video: C-SPAN ] The Miami Herald is referring to the group of senators as the “Gang of Eight.” The new immigration deal will be announced officially on Monday afternoon.
