Senate Democrats have the votes to block the short-term spending bill being considered by the House, according to a senior Senate Democratic aide, increasing the chances of a partial government shutdown.

Only one Senate Democrat, Joe Manchin D-W.Va., has said publicly they'd support the stopgap measure to the keep the government funded until Feb. 16. But a growing number of Senate Democrats announced opposition Thursday, saying they wouldn't vote for the continuing resolution because it doesn't include a fix for so-called Dreamers and creates uncertainty for agencies and the military.

“We oppose the House continuing resolution," Virginia Democratic Sens. Tim Kaine and Mark Warner said in a joint statement. "Congress should remain in session with no recess until we work out a long-term bipartisan budget deal that addresses all issues."

Kaine and Warner voted for a short-term funding measure in December that runs out Friday night, but said "perpetuating" the current "budgetary dysfunction" harms the nation and their state.

Democrats in both chambers have voiced frustrations over the lack of bipartisan negotiations. The short-term funding bill was crafted by Republican leaders in the House and proposals for a smaller five-day measure have been shot down by Republicans.

Sens. Lindsey Graham, R-S.C., Mike Rounds, R-S.D., and Rand Paul, R-Ky., also plan to vote against the measure. Sen. Mike Lee, R-Utah, may oppose it as well.

House Speaker Paul Ryan is confident he has the votes to pass the continuing resolution in the House, but conservatives who oppose the measure could cause complications.
