As we first noted last night, House Republicans need at least 217 votes to pass Speaker John A. Boehner's "Plan B" to raise taxes on people earning more than $1 million annually.

Currently there are two House vacancies and 241 total Republicans. That means if every member shows up for the vote today, the conference can spare 24 defections and still deliver a majority without Democratic support.

But a count being maintained by The Hill newspaper suggests "Plan B" is on the verge of failure. Based on interviews with members and their votes for or against the rule establishing debate of "Plan B," the newspaper counts at least 25 GOP lawmakers firmly or leaning towards voting "no" for Boehner's bill.

This preliminary whip count does not mean that lawmakers ultimately will vote against the bill, especially if it is possible that their votes could tip the scales in either direction.

Here's The Hill's list, as of 4:21 p.m. ET:

Justin Amash (Mich.) Will vote no; voted against the rule
