Sen. Jim DeMint (R-S.C.) said the vote on whether or not to ban earmarks will be the first test as to whether members fully grasp the lessons of the midterm elections.
The Republican Conference is scheduled to vote on the ban at their weekly meeting Tuesday.

DeMint hinted Monday that Republicans who aren't supportive of the ban could face trouble if they have to face voters in two years, but said he's confident the ban will win approval on Tuesday, led by the newly-elected crop of GOP Senators.
"2012 is going to make what just happened look small if we continue what we started," DeMint predicted.
Voters listed a reduction in spending as one of their top concerns this election cycle; several Republican candidates ran successful campaigns based on that issue.
DeMint entered the gathering Monday, sponsored by the conservative group Americans for Prosperity, to shouts of "DeMint for president," eliciting a broad smile from the South Carolina Republican.
Through his Senate Conservatives Fund, DeMint helped raised several million dollars for Tea Party backed candidates in 2010 and played a leading role in several high-profile GOP primary fights.
