The Employee Free Choice Act was introduced in Congress Tuesday, as its key supporters in the Senate are beginning to express doubt. The Wall Street Journal lists Senators Blanche Lincoln (D. Ark.), Mark Pryor (D. Ark.), Mary Landrieu (D. La.), and Arlen Specter (R.

These splits among Democrats underscore how difficult it will be for the Employee Free Choice Act, in its current form, to garner the 60 votes needed to avoid another Senate filibuster.
