No, there are 49 Reps, 48 Dems, 1 Ind, and 1 Socialist. The Reps are technically the majority party now, but the two odds are caucusing with the Dems.

Actually in that case the Republicans would be the plurality party, not the majority. And since Searchlight will get the support of the I and the S, he'll be the Majority Leader.

Yes, plurality, not majority. I stand corrected: there is no current majority party in the Senate.
