Today marks the last day of this year's legislative session, with the bulk of the business done but a few loose threads still waiting to be tied up.

The session is ending on a note of intrigue as Lt. Gov. Glenn McConnell prepares to leave his post to assume the presidency of the College of Charleston and Sen. John Courson, R-Columbia, stepped down as Senate President Pro Tem - a far more powerful position - to avoid become the next lieutenant governor.

Meanwhile, a Clemson poll released Wednesday, probably the last public poll before Tuesday's primaries, showed U.S. Sen. Lindsey Graham with 49 percent but none of his challengers above 8 percent. It adds an element of intrigue to the question of whether Graham can crack the 50-percent plus one mark necessary to avoid a June 24 runoff.

Here's our story: Graham could win without runoff, Clemson poll suggests.

Later today, South Carolina's big political event will unfold in Columbia as the four Republican candidates for lieutenant governor: Mike Campbell, Pat McKinney, Henry McMaster and Ray Moore debate one another.

The debate is scheduled to air at 7 p.m. on ETV-HD and will stream live on scetv.org.
