WASHINGTON (AP) — House members who are willing to give their positions are either opposed to or leaning against President Barack Obama's plan for a U.S. military strike against Syria by nearly a 6-to-1 margin. That's the finding of a survey by The Associated Press. The Senate is more evenly divided.

Despite the indications that Obama faces an uphill fight in votes as early as next week, the situation is very fluid. About half of the 433-member House and a third of the 100-member Senate remain undecided.

By their own statements or those of their aides, only 31 members of the Republican-led House support intervention or are leaning in favor of authorizing force. Some 185 House members outright oppose U.S. military involvement or are leaning against it.
