The Senate this week is expected to approve a bipartisan deal to renew expired benefits for the long-term unemployed.

A few weeks back, we detailed how the deal would interact with state policies to affect the jobless across the nation (see map above) and on Tuesday, our colleagues over at The Fix explain how we got here — and why the Senate deal is unlikely to go anywhere in the House.

The recent recession inflated the ranks of the long-term unemployed — those out of work for roughly six months or more — to levels never before seen. And while the situation has improved some, the share of the unemployed who have been out of work for a long stretch remains well above its historical record.

The Senate deal seeks to reinstate benefits for that population that were allowed to expire at the end of 2013. How did this deal come to be? Ed O’Keefe explains:

Democrats and a small handful of Republicans have been working together since late December to strike a new deal that would restart the benefits and pay for them in a way that Republicans could live with — through May. Talks have been led by Sens. Jack Reed (D-R.I.) and Dean Heller (R-Nev.), who represent the two states with the highest levels of unemployment in the country.
