U.S. Sen. Lindsey Graham has a TV spot out promoting his support for the Port of Charleston. In one segment is a shot that prominently features U.S. Sen. Tim Scott standing nearby.

Scott - regarded one of the most popular Republicans in the state - said he had no issue with his image or likeness being used in another candidate's TV advertising, even as Graham faces his fiercest competition yet against six other GOP challengers on June 10, many with tea party support.

The key factor, Scott said, is how events are portrayed, saying he would be concerned if there were inconsistencies of facts.

In this case, Scott said he and Graham have worked together to protect port efforts, so he has no dispute with how the commercial is presented.

Scott, otherwise, has opted not to play a role in Graham's re-election, including choosing not to make an endorsement in the primary.

Could Mignon Clyburn of Charleston -daughter of U.S. Rep. James Clyburn -be the next chair of the Federal Communications Commission?

She currently serves as one of five FCC commissioners - and one of two who recently voted against a network neutrality rule that would allow Internet service providers like AT&T, Comcast and Verizon to create "fast lanes" so monopolies and large companies could pay extra for special treatment. The FCC will take public comment before this summer before making a final ruling.

Zephyr Teachout, a New America Foundation and Fordham Law School professor, wrote an op-ed for Politico last week suggesting that President Barack Obama isn't happy with current FCC chair's Tom Wheeler's efforts. The White House statement said only that the FCC is "an independent agency," adding, "We will be watching closely as the process moves forward in hopes that the final rule stays true to the spirit of net neutrality."

Teachout noted while Obama can't fire any commissioners in the middle of their five-year terms, he does have the power to remove Wheeler from the chairmanship in favor of one of the other four commissioners.

"In particular, both Mignon Clyburn and Jessica Rosenworcel, the two other Democrats on the five-person board, spoke out eloquently in official statements on Thursday, criticizing Wheeler's proposal for authorizing fast lanes and being a 'network neutrality' rule in name only," Teachout wrote. "Either Clyburn or Rosenworcel could take over the agency, scrap Wheeler's plan in favor of an alternative and move quickly to ensure an open Internet, thereby fulfilling the cornerstone of the Obama campaign's tech agenda after the four-month comment period."

While Teachout said firing Wheeler as chairman would be an unusual move, she cited several reasons Obama should do it.

The level of interest in absentee voting is way off this year from the participation seen four years ago.

"Not too hot," said Joe Debney, executive director of the Charleston County Board of Elections and Voter Registration.

In 2010, there were 2,359 absentee votes cast in the primary. But so far this year the office has issued 1,753 applications for absentee voting, only 323 of which have been returned.

One reason for the low interest, Debney said, is there are no primary fights for governor as there was four years ago.

The downside, he added, is that the state's two U.S. Senate races just don't seem to be generating that much interest.

Tuesday, June 24 could be a collision of political events in South Carolina.

For starters, that's the date the state Supreme Court has set to hear a challenge of a judge's dismissal of Attorney General Alan Wilson's efforts to get a State Grand Jury to investigate corruption allegations against House Speaker Bobby Harrell, R-Charleston.

It's also the date set for when tens of thousands of voters would go to the polls for a second time in June to settle any runoffs that come out of the June 10 Republican and Democratic primaries.

Runoffs are likely in a variety of statewide races, including party battles for U.S. Senate, the GOP race for education superintendent, and the Republican race for lieutenant governor.

Runoffs are called if candidates don't collect better than 50 percent of the vote in multi-candidate fields during the first go-round.
