Input: Washington (CNN) -- A federal budget compromise that already passed the House cleared a key procedural hurdle on Tuesday in the Senate, increasing the likelihood it will win final Congressional approval this week. President Barack Obama has signaled his support for the plan worked out by the budget committee leaders in each chamber that would guide government spending into 2015 to defuse the chances of another shutdown such as the one that took place in October. Tuesday's vote overcame a Republican filibuster attempt that required 60 votes in the 100-member chamber to proceed on the budget measure. The count was 67-33, with a dozen Republicans joining the 55 Democrats and independents in support of the plan.NEW: A new poll shows public support for the budget deal12 Republicans join Democrats in overcoming a filibuster attemptBill aims to avert another government shutdown as early as mid-JanuaryThe House already passed the compromise budget plan
