Exclamation point….
Check it out:

Republican Rep. Bill Cassidy has denied Democratic Sen. Mary Landrieu of Louisiana a fourth term, calling his Senate victory “the exclamation point” on midterm elections that put Republicans in charge on Capitol Hill for President Barack Obama’s last two years in office.

With nearly all votes counted, unofficial returns showed Cassidy with a commanding victory in Saturday’s runoff as he ousted the last of the Senate’s Deep South Democrats. In the South, Democrats will be left without a single U.S. senator or governor across nine states stretching from the Carolinas to Texas.
